The
LM7321/LM7321Q/LM7322/LM7322Q
are
designed to drive unlimited capacitive loads without
oscillations.
All
LM7321/LM7321Q
and
LM7322/LM732Q parts are tested at −40°C, 125°C,
and 25°C, with modern automatic test equipment.
High performance from −40°C to 125°C, detailed
specifications, and extensive testing makes them
suitable
for
industrial,
automotive,
and
communications applications.
Greater than rail-to-rail input common mode voltage
range with 50 dB of common mode rejection across
this wide voltage range, allows both high side and low
side sensing. Most device parameters are insensitive
to power supply voltage, and this makes the parts
easier to use where supply voltage may vary, such as
automotive electrical systems and battery powered
equipment. These amplifiers have true rail-to-rail
output and can supply a respectable amount of
current (15 mA) with minimal head- room from either
rail (300 mV) at low distortion (0.05% THD+Noise).
There are several package options for each part.
Standard SOIC versions of both parts make
upgrading existing designs easy. LM7322LM7322Q
are offered in a space saving 8-Pin VSSOP package.
The LM7321/LM7321Q are offered in small SOT-23
package, which makes it easy to place this part close
to sensors for better circuit performance.

Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device such that TJ = TA. No ensured specification of parametric performance is indicated in the electrical
tables under conditions of internal self-heating where TJ > TA.
All limits are ensured by testing or statistical analysis.
Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
Offset voltage temperature drift determined by dividing the change in VOS at temperature extremes into the total temperature change.
Positive current corresponds to current flowing into the device.
Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in

APPLICATION INFORMATION
DRIVING CAPACITIVE LOADS
The LM7321/LM7321Q/LM7322/LM7322Q are specifically designed to drive unlimited capacitive loads without
oscillations as shown in Figure 64.
Figure 64. ±5% Settling Time vs. Capacitive Load
In addition, the output current handling capability of the device allows for good slewing characteristics even with
large capacitive loads as shown in Figure 65 and Figure 66.

Figure 66. −SR vs. Capacitive Load
The combination of these features is ideal for applications such as TFT flat panel buffers, A/D converter input
amplifiers, etc.
However, as in most op amps, addition of a series isolation resistor between the op amp and the capacitive load
improves the settling and overshoot performance.
Output current drive is an important parameter when driving capacitive loads. This parameter will determine how
fast the output voltage can change. Referring to the Slew Rate vs. Capacitive Load Plots (Typical Performance
Characteristics section), two distinct regions can be identified. Below about 10,000 pF, the output Slew Rate is
solely determined by the op amp’s compensation capacitor value and available current into that capacitor.
Beyond 10 nF, the Slew Rate is determined by the op amp’s available output current. Note that because of the
lower output sourcing current compared to the sinking one, the Slew Rate limit under heavy capacitive loading is
determined by the positive transitions. An estimate of positive and negative slew rates for loads larger than 100
nF can be made by dividing the short circuit current value by the capacitor.
For the LM7321/LM7321Q/LM7322/LM7322Q, the available output current increases with the input overdrive.
Referring to Figure 67 and Figure 68, Output Short Circuit Current vs. Input Overdrive, it can be seen that both
sourcing and sinking short circuit current increase as input overdrive increases. In a closed loop amplifier
configuration, during transient conditions while the fed back output has not quite caught up with the input, there
will be an overdrive imposed on the input allowing more output current than would normally be available under
steady state condition. Because of this feature, the op amp’s output stage quiescent current can be kept to a
minimum, thereby reducing power consumption, while enabling the device to deliver large output current when
the need arises (such as during transients).

Figure 69 shows the output voltage, output current, and the resulting input overdrive with the device set for AV =
+1 and the input tied to a 1 VPP step function driving a 47 nF capacitor. As can be seen, during the output
transition, the input overdrive reaches 1V peak and is more than enough to cause the output current to increase
to its maximum value (see Figure 67 and Figure 68 plots). Note that because of the larger output sinking current
compared to the sourcing one, the output negative transition is faster than the positive one.

ESTIMATING THE OUTPUT VOLTAGE SWING
It is important to keep in mind that the steady state output current will be less than the current available when
there is an input overdrive present. For steady state conditions, the Output Voltage vs. Output Current plot
(Typical Performance Characteristics section) can be used to predict the output swing. Figure 70 and Figure 71
show this performance along with several load lines corresponding to loads tied between the output and ground.
In each cases, the intersection of the device plot at the appropriate temperature with the load line would be the
typical output swing possible for that load. For example, a 1 kΩ load can accommodate an output swing to within
250 mV of V− and to 330 mV of V+ (VS = ±15V) corresponding to a typical 29.3 VPP unclipped swing.

SETTLING TIME WITH LARGE CAPACITIVE LOADS
Figure 72 below shows a typical application where the LM7321/LM7321Q/LM7322/LM7322Q is used as a buffer
amplifier for the VCOM signal employed in a TFT LCD flat panel:
Figure 72. VCOM Driver Application Schematic
Figure 73 shows the time domain response of the amplifier when used as a VCOM buffer/driver with VREF at
ground. In this application, the op amp loop will try and maintain its output voltage based on the voltage on its
non-inverting input (VREF) despite the current injected into the TFT simulated load. As long as this load current is
within the range tolerable by the LM7321/LM7321Q/LM7322/LM7322Q (45 mA sourcing and 65 mA sinking for
±5V supplies), the output will settle to its final value within less than 2 μs.

OUTPUT SHORT CIRCUIT CURRENT AND DISSIPATION ISSUES
The LM7321/LM7321Q/LM7322/LM7322Q output stage is designed for maximum output current capability. Even
though momentary output shorts to ground and either supply can be tolerated at all operating voltages, longer
lasting short conditions can cause the junction temperature to rise beyond the absolute maximum rating of the
device, especially at higher supply voltage conditions. Below supply voltage of 6V, the output short circuit
condition can be tolerated indefinitely.
With the op amp tied to a load, the device power dissipation consists of the quiescent power due to the supply
current flow into the device, in addition to power dissipation due to the load current. The load portion of the
power itself could include an average value (due to a DC load current) and an AC component. DC load current
would flow if there is an output voltage offset, or the output AC average current is non-zero, or if the op amp
operates in a single supply application where the output is maintained somewhere in the range of linear
operation.
Therefore:
PTOTAL = PQ + PDC + PAC
PQ = IS · VS
Op Amp Quiescent Power Dissipation
PDC = IO · (Vr - Vo)
DC Load Power
PAC = See Table 1
AC Load Power
where:
IS: Supply Current
VS: Total Supply Voltage (V+ − V−)
VO: Average Output Voltage
Vr: V+ for sourcing and V− for sinking current
Table 1 shows the maximum AC component of the load power dissipated by the op amp for standard Sinusoidal,
Triangular, and Square Waveforms:

The table entries are normalized to VS2/RL. To figure out the AC load current component of power dissipation,
simply multiply the table entry corresponding to the output waveform by the factor VS2/RL. For example, with
±12V supplies, a 600Ω load, and triangular waveform power dissipation in the output stage is calculated as:
PAC = (46.9 x 10−3) · (242/600) = 45.0 mW
(1)
The maximum power dissipation allowed at a certain temperature is a function of maximum die junction
temperature (TJ(MAX)) allowed, ambient temperature TA, and package thermal resistance from junction to ambient,
θJA.
TJ(MAX) - TA
PD(MAX) =
TJA
(2)
For the LM7321/LM7321Q/LM7322/LM7322Q, the maximum junction temperature allowed is 150°C at which no
power dissipation is allowed. The power capability at 25°C is given by the following calculations:
For VSSOP package:
PD(MAX) =
150°C ± 25°C
= 0.53W
235°C/W
(3)
For SOIC package:
PD(MAX) =
150°C ± 25°C
= 0.76W
165°C/W
(4)
Similarly, the power capability at 125°C is given by:
For VSSOP package:
PD(MAX) =
150°C ± 125°C
= 0.11W
235°C/W
(5)
For SOIC package:
PD(MAX) =
150°C ± 125°C
= 0.15W
165°C/W
(6)
Figure 74 shows the power capability vs. temperature for VSSOP and SOIC packages. The area under the
maximum thermal capability line is the operating area for the device. When the device works in the operating
area where PTOTAL is less than PD(MAX), the device junction temperature will remain below 150°C. If the
intersection of ambient temperature and package power is above the maximum thermal capability line, the
junction temperature will exceed 150°C and this should be strictly prohibited.

Other Application Hints
The use of supply decoupling is mandatory in most applications. As with most relatively high speed/high output
current Op Amps, best results are achieved when each supply line is decoupled with two capacitors; a small
value ceramic capacitor (∼0.01 μF) placed very close to the supply lead in addition to a large value Tantalum or
Aluminum (> 4.7 μF). The large capacitor can be shared by more than one device if necessary. The small
ceramic capacitor maintains low supply impedance at high frequencies while the large capacitor will act as the
charge "bucket" for fast load current spikes at the op amp output. The combination of these capacitors will
provide supply decoupling and will help keep the op amp oscillation free under any load.

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.
