FEATURES
DESCRIPTION
•
•
The INA199 series of voltage output current shunt
monitors can sense drops across shunts at commonmode voltages from –0.3V to 26V, independent of the
supply voltage. Three fixed gains are available:
50V/V, 100V/V, and 200V/V. The low offset of the
Zerø-Drift architecture enables current sensing with
maximum drops across the shunt as low as 10mV
full-scale.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATION INFORMATION
BASIC CONNECTIONS
Figure 20 shows the basic connections for the INA199. The input pins, IN+ and IN–, should be connected as
closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistance.

Figure 20. Typical Application
Power-supply bypass capacitors are required for stability. Applications with noisy or high-impedance power
supplies may require additional decoupling capacitors to reject power-supply noise. Connect bypass capacitors
close to the device pins.
On the RSW package, two pins are provided for each input. These pins should be tied together (that is, tie IN+ to
IN+ and tie IN– to IN–).
POWER SUPPLY
The input circuitry of the INA199 can accurately measure beyond its power-supply voltage, V+. For example, the
V+ power supply can be 5V, whereas the load power-supply voltage can be as high as +26V. However, the
output voltage range of the OUT terminal is limited by the voltages on the power-supply pin. Note also that the
INA199 can withstand the full –0.3V to +26V range in the input pins, regardless of whether the device has power
applied or not.
SELECTING RS
The zero-drift offset performance of the INA199 offers several benefits. Most often, the primary advantage of the
low offset characteristic enables lower full-scale drops across the shunt. For example, non-zero-drift current
shunt monitors typically require a full-scale range of 100mV.
The INA199 series of current-shunt monitors give equivalent accuracy at a full-scale range on the order of 10mV.
This accuracy reduces shunt dissipation by an order of magnitude with many additional benefits.
Alternatively, there are applications that must measure current over a wide dynamic range that can take
advantage of the low offset on the low end of the measurement. Most often, these applications can use the lower
gain of 50 or 100 to accommodate larger shunt drops on the upper end of the scale. For instance, an INA199A1
operating on a 3.3V supply could easily handle a full-scale shunt drop of 60mV, with only 150μV of offset.

UNIDIRECTIONAL OPERATION
Unidirectional operation allows the INA199 to measure currents through a resistive shunt in one direction. The
most frequent case of unidirectional operation sets the output at ground by connecting the REF pin to ground. In
unidirectional applications where the highest possible accuracy is desirable at very low inputs, bias the REF pin
to a convenient value above 50mV to get the device output swing into the linear range for zero inputs.
A less frequent case of unipolar output biasing is to bias the output by connecting the REF pin to the supply; in
this case, the quiescent output for zero input is at quiescent supply. This configuration would only respond to
negative currents (inverted voltage polarity at the device input).
BIDIRECTIONAL OPERATION
Bidirectional operation allows the INA199 to measure currents through a resistive shunt in two directions. In this
case, the output can be set anywhere within the limits of what the reference inputs allow (that is, between 0V to
V+). Typically, it is set at half-scale for equal range in both directions. In some cases, however, it is set at a
voltage other than half-scale when the bidirectional current is nonsymmetrical.
The quiescent output voltage is set by applying voltage to the reference input. Under zero differential input
conditions the output assumes the same voltage that is applied to the reference input.
INPUT FILTERING
An obvious and straightforward filtering location is at the device output. However, this location negates the
advantage of the low output impedance of the internal buffer. The only other filtering option is at the device input
pins. This location, though, does require consideration of the ±30% tolerance of the internal resistances.
Figure 21 shows a filter placed at the inputs pins.

Figure 21. Filter at Input Pins
The addition of external series resistance, however, creates an additional error in the measurement so the value
of these series resistors should be kept to 10Ω or less if possible to reduce impact to accuracy. The internal bias
network shown in Figure 21 present at the input pins creates a mismatch in input bias currents when a
differential voltage is applied between the input pins. If additional external series filter resistors are added to the
circuit, the mismatch in bias currents results in a mismatch of voltage drops across the filter resistors. This
mismatch creates a differential error voltage that subtracts from the voltage developed at the shunt resistor. This
error results in a voltage at the device input pins that is different than the voltage developed across the shunt
resistor. Without the additional series resistance, the mismatch in input bias currents has little effect on device
operation. The amount of error these external filter resistor add to the measurement can be calculated using
Equation 2 where the gain error factor is calculated using Equation 1.

SBOS469D – MAY 2009 – REVISED NOVEMBER 2012
The amount of variance in the differential voltage present at the device input relative to the voltage developed at
the shunt resistor is based both on the external series resistance value as well as the internal input resistors, R3
and R4 (or RINT as shown in Figure 21). The reduction of the shunt voltage reaching the device input pins
appears as a gain error when comparing the output voltage relative to the voltage across the shunt resistor. A
factor can be calculated to determine the amount of gain error that is introduced by the addition of external series
resistance. The equation used to calculate the expected deviation from the shunt voltage to what is seen at the
device input pins is given in Equation 1:
(1250 ´ RINT)
Gain Error Factor =
(1250 ´ RS) + (1250 ´ RINT) + (RS ´ RINT)
where:
RINT is the internal input resistor (R3 and R4), and
RS is the external series resistance.
(1)
With the adjustment factor equation including the device internal input resistance, this factor varies with each
gain version, as shown in Table 1. Each individual device gain error factor is shown in Table 2.

The gain error that can be expected from the addition of the external series resistors can then be calculated
based on Equation 2:
Gain Error (%) = 100 - (100 ´ Gain Error Factor)
(2)
For example, using an INA199A2 or INA199B2 and the corresponding gain error equation from Table 2, a series
resistance of 10Ω results in a gain error factor of 0.991. The corresponding gain error is then calculated using
Equation 2, resulting in a gain error of approximately 0.89% solely because of the external 10Ω series resistors.
Using an INA199A1 or INA199B1 with the same 10Ω series resistor results in a gain error factor of 0.991 and a
gain error of 0.84% again solely because of these external resistors.

SHUTTING DOWN THE INA199 SERIES
While the INA199 series does not have a shutdown pin, the low power consumption allows powering from the
output of a logic gate or transistor switch that can turn on and turn off the INA199 power-supply quiescent
current.
However, in current shunt monitoring applications. there is also a concern for how much current is drained from
the shunt circuit in shutdown conditions. Evaluating this current drain involves considering the simplified
schematic of the INA199 in shutdown mode shown in Figure 22.

NOTE: 1MΩ paths from shunt inputs to reference and INA199 outputs.
Figure 22. Basic Circuit for Shutting Down INA199 with Grounded Reference
Note that there is typically slightly more than 1MΩ impedance (from the combination of 1MΩ feedback and 5kΩ
input resistors) from each input of the INA199 to the OUT pin and to the REF pin. The amount of current flowing
through these pins depends on the respective ultimate connection. For example, if the REF pin is grounded, the
calculation of the effect of the 1MΩ impedance from the shunt to ground is straightforward. However, if the
reference or op amp is powered while the INA199 is shut down, the calculation is direct; instead of assuming
1MΩ to ground, however, assume 1MΩ to the reference voltage. If the reference or op amp is also shut down,
some knowledge of the reference or op amp output impedance under shutdown conditions is required. For
instance, if the reference source behaves as an open circuit when it is unpowered, little or no current flows
through the 1MΩ path.
Regarding the 1MΩ path to the output pin, the output stage of a disabled INA199 does constitute a good path to
ground; consequently, this current is directly proportional to a shunt common-mode voltage impressed across a
1MΩ resistor.
As a final note, when the device is powered up, there is an additional, nearly constant, and well-matched 25μA
that flows in each of the inputs as long as the shunt common-mode voltage is 3V or higher. Below 2V commonmode, the only current effects are the result of the 1MΩ resistors.

REF INPUT IMPEDANCE EFFECTS
As with any difference amplifier, the INA199 series common-mode rejection ratio is affected by any impedance
present at the REF input. This concern is not a problem when the REF pin is connected directly to most
references or power supplies. When using resistive dividers from the power supply or a reference voltage, the
REF pin should be buffered by an op amp.
In systems where the INA199 output can be sensed differentially, such as by a differential input analog-to-digital
converter (ADC) or by using two separate ADC inputs, the effects of external impedance on the REF input can
be cancelled. Figure 23 depicts a method of taking the output from the INA199 by using the REF pin as a
reference.

USING THE INA199 WITH COMMON-MODE TRANSIENTS ABOVE 26V
With a small amount of additional circuitry, the INA199 series can be used in circuits subject to transients higher
than 26V, such as automotive applications. Use only zener diode or zener-type transient absorbers (sometimes
referred to as Transzorbs); any other type of transient absorber has an unacceptable time delay. Start by adding
a pair of resistors as shown in Figure 24 as a working impedance for the zener. It is desirable to keep these
resistors as small as possible, most often around 10Ω. Larger values can be used with an effect on gain that is
discussed in the section on input filtering. Because this circuit limits only short-term transients, many applications
are satisfied with a 10Ω resistor along with conventional zener diodes of the lowest power rating that can be
found. This combination uses the least amount of board space. These diodes can be found in packages as small
as SOT-523 or SOD-523.

In the event that low-power zeners do not have sufficient transient absorption capability and a higher power
transzorb must be used, the most package-efficient solution then involves using a single transzorb and back-toback diodes between the device inputs. This method is shown in Figure 25. The most space-efficient solutions
are dual series-connected diodes in a single SOT-523 or SOD-523 package. In both examples shown in
Figure 24 and Figure 25, the total board area required by the INA199 with all protective components is less than
that of an SO-8 package, and only slightly greater than that of an MSOP-8 package.

IMPROVING TRANSIENT ROBUSTNESS
Applications involving large input transients with excessive dV/dt above 2kV per microsecond present at the
device input pins may cause damage to the internal ESD structures on version A devices. This potential damage
is a result of the internal latching of the ESD structure to ground when this transient occurs at the input. With
significant current available in most current-sensing applications, the large current flowing through the input
transient-triggered, ground-shorted ESD structure quickly results in damage to the silicon. External filtering can
be used to attenuate the transient signal prior to reaching the inputs to avoid the latching condition. Care must be
taken to ensure that external series input resistance does not significantly impact gain error accuracy. For
accuracy purposes, these resistances should be kept under 10Ω if possible. Ferrite beads are recommended for
this filter because of their inherently low dc ohmic value. Ferrite beads with less than 10Ω of resistance at dc and
over 600Ω of resistance at 100MHz to 200MHz are recommended. The recommended capacitor values for this
filter are between 0.01µF and 0.1µF to ensure adequate attenuation in the high-frequency region. This protection
scheme is shown in Figure 26.

Figure 26. Transient Protection
To minimize the cost of adding these external components to protect the device in applications where large
transient signals may be present, version B devices are now available with new ESD structures that are not
susceptible to this latching condition. Version B devices are incapable of sustaining these damage causing
latched conditions so they do not have the same sensitivity to the transients that the version A devices have,
thus making the version B devices a better fit for these applications.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
