MAX6070/MAX6071
Low-Noise, High-Precision Series
Voltage References
General Description
Benefits and Features
The MAX6070/MAX6071 offer a very low noise and
low-drift voltage reference in a small 6-pin SOT23 pack-
age. These devices provide a 1/f noise voltage of only
S High Q0.04% Initial Accuracy
S Low 1.5ppm/°C (typ), 6ppm/°C (max) Temperature
Drift
4.8µV
at an output voltage of 2.5V, with a temperature
P-P
S Low 4.8µV
Noise (0.1Hz to 10Hz) at 2.5V
P-P
drift of 6ppm/NC (max). The devices operate with an input
voltage from 2.8V to 5.5V. The MAX6070/MAX6071 con-
sume 150FA of supply current and can sink and source
up to 10mA of load current. The MAX6070/MAX6071 pro-
vide an initial accuracy of 0.04%. 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.
S Low 150µA Supply Current
S 10mA Source/Sink Load Current
S Noise Filter Option
S Low 200mV Dropout Voltage
S High 85dB Ripple Rejection
S Small 6-Pin SOT23 Package
S Voltage Output Options: 1.25V, 1.8V, 2.048V, 2.5V,
The MAX6070/MAX6071 provide output voltages of
1.25V, 1.8V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V.
The devices are available in a 6-pin SOT23 package and
specified over the extended industrial temperature range
of -40NC to +125NC.
3.0V, 3.3V, 4.096V, and 5.0V
Ordering Information and Selector Guide appears at end of
data sheet.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion 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.

Detailed Description
tures 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).
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.
Shutdown
The MAX6070/MAX6071 feature an active-high enable
pin (EN). Pulling EN low disables the output with a resis-
tive 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.
Applications Information
Output Bypassing
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 cur-
rents, 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.
Wideband Noise Reduction
shows a typical noise reduction filter application
circuit. Note that the use of the wideband noise filter will
increase turn-on time.

Reference from a Single Supply
Figure 2
shows a typical circuit providing the reference
for a high-resolution, 16-bit MAX541 DAC.
Supply Current
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.
Precision Current Source
shows a typical circuit providing a precision cur-

rent source. The OUTF output provides the bias current
for the bipolar transistor. OUTS and GNDS sense the volt-
age across the resistor and adjust the current sourced by
OUTF accordingly.
Thermal Hysteresis
Thermal hysteresis is the change of output voltage at
T = +25NC before and after the device is cycled over its
A
entire operating temperature range. The typical thermal
hysteresis value is 85ppm.
5V SUPPLY
Turn-On Time
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.

Output Force and Sense
The MAX6070/MAX6071 provide independent connec-
tions 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 connect-
ing 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
connect OUTS to OUTF at the point where the voltage
