General Description
The MAX6070/MAX6071 offer a very low noise and
low-drift voltage reference in a small 6-pin SOT23 package. These devices provide a 1/f noise voltage of only
4.8µVP-P at an output voltage of 2.5V, with a temperature
drift of 6ppm/NC (max). The MAX6070/MAX6071 consume 150FA of supply current and can sink and source
up to 10mA of load current. The low-drift and low-noise
specifications enable enhanced system accuracy, making
these devices ideal for high precision industrial applications. The MAX6070 offers a noise filter option for wideband applications.
The devices are available in a 6-pin SOT23 package and
specified over the extended industrial temperature range
of ‑40NC to +125NC.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

Note 2: Limits are 100% production tested at TA = +25°C. Specifications where TA < +25°C or TA > +25°C are guaranteed by
design and characterization.
Note 3: Temperature coefficient is calculated using the “box method” which measures temperature drift as the maximum voltage
variation over a specified temperature range. The unit of measurement is ppm/°C.
Note 4: Dropout voltage is defined as the minimum differential voltage (VIN - VOUT) at which VOUT decreases by 0.2% from its
original value at VIN = 5.0V.
Note 5: Thermal hysteresis is defined as the change in +25NC output voltage before and after cycling the device from TMAX to TMIN.
Note 6: Dropout voltage is defined as the minimum differential voltage (VIN – VOUT) at which VOUT decreases by 0.2% from its
original value at VIN = 5.5V.

MAX6070/MAX6071
Detailed Description
Wideband Noise Reduction (FILTER)
To improve wideband noise and transient power-supply
noise with the MAX6070, connect a 0.1FF capacitor from
FILTER to GND (see the Typical Operating Characteristics).
Larger values do not appreciably improve noise reduction.
A 0.1FF capacitor reduces the spectral noise density at
1kHz from 60nV/√Hz to 30nV/√Hz for the 2.5V output.
Noise at the input pin can affect output noise, but can
be reduced by connecting an optional bypass capacitor
between IN and GND as shown in Figure 1.
Output Bypassing
Low-Noise, High-Precision Series
Voltage References
connect OUTS to OUTF at the point where the voltage
accuracy is needed (see Figure 1). The MAX6071 features the same type of Kelvin connection to cancel drops
in the ground return line. Connect the load to ground and
connect GNDS to ground as close as possible to the load
ground connection (see Figure 2).
Shutdown
The MAX6070/MAX6071 feature an active-high enable
pin (EN). Pulling EN low disables the output with a resistive load to ground and forces the quiescent current to
less than 1µA. The value of the load is typically 200kω.
Pulling EN high enables normal operation.
The MAX6070/MAX6071 require an output capacitor
between 0.1FF and 10FF. Place the output capacitor
as close to OUTF as possible. For applications driving
switching capacitive loads or rapidly changing load currents, use a 0.1µF capacitor in parallel with a larger load
capacitor to reduce equivalent series resistance (ESR).
Larger capacitor values and lower ESR reduce transients
on the reference output.
Applications Information
Supply Current
Figure 2 shows a typical circuit providing the reference for
a high-resolution, 16-bit MAX541 DAC.
The MAX6070/MAX6071 draw 150FA of current and are
virtually independent of the supply voltage, with only a
1.6FA /V variation with supply voltage.
Thermal Hysteresis
Thermal hysteresis is the change of output voltage at
TA = +25NC before and after the device is cycled over its
entire operating temperature range. The typical thermal
hysteresis value is 85ppm.
Wideband Noise Reduction
Figure 1 shows a typical noise reduction filter application
circuit. Note that the use of the wideband noise filter will
increase turn-on time.
High-Resolution DAC and
Reference from a Single Supply
Precision Current Source
Figure 3 shows a typical circuit providing a precision current source. The OUTF output provides the bias current
for the bipolar transistor. OUTS and GNDS sense the
voltage across the resistor and adjust the current sourced
by OUTF accordingly.
Turn-On Time
5V SUPPLY
These devices typically turn on and settle to within 0.01%
of their final value in 30Fs. A noise reduction capacitor of
0.1FF increases the turn-on time of the MAX6070 to 10ms.
EN
Output Force and Sense
The MAX6070/MAX6071 provide independent connections for the force output (OUTF) supplying current to the
load and the circuit input regulating the load voltage via
the output sense pin (OUTS). This configuration allows for
the cancellation of the voltage drop on the lines connecting the MAX6070/MAX6071 and the load. When using
the Kelvin connection made possible by the independent
force and sense outputs, connect OUTF to the load and
