MAX6070/MAX6071
Low-Noise, High-Precision Series
Voltage References
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
Benefits and Features
● 6-Pin SOT23 Package Reduces System Board Space
● Stable Performance Over Temperature and Time
Improves System Accuracy
4.8µV
at an output voltage of 2.5V, with a temperature
P-P
• High ±0.04% Initial Accuracy
• Low 1.5ppm/°C (typ), 6ppm/°C (max) Temperature
Drift
drift of 6ppm/NC (max). The devices 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.
• Low 4.8μV
Noise (0.1Hz to 10Hz) at 2.5V
P-P
• Low 200mV Dropout Voltage
• High 85dB Ripple Rejection
● Low 150μA Supply Current Reduces Power
The devices are available in a 6-pin SOT23 package and
are specified over the extended industrial temperature
range of -40NC to +125NC. The 2.5V options are also
available in a 6-bump 0.78mm x 1.41mm wafer-level
package (WLP).
Consumption
● Filter Option Lowers High-Frequency Noise
● Output Options: 1.25V, 1.8V, 2.048V, 2.5V, 3.0V,
3.3V, 4.096V, and 5.0V Cover Common Voltage
Levels for a Wide Variety of Applications
Applications
● High-Accuracy Industrial and Process Control
● Precision Instrumentation
● 0.78mm x 1.41mm WLP with 0.35mm Bump Spacing
● AEC-Q100 Qualified (Refer to Ordering Information)
● High-Resolution ADCs and DACs
● Precision Current Sources
● Automotive
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 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.

For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”,
“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.

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).
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.
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.
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.
Applications Information
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
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.
Precision Current Source
Figure 3 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
voltage 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.
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.

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

Long-Term Drift and Humidity Effects
There are many factors that contribute to a voltage
reference’s drift over time. These can include package
stress, board stress and layout, humidity and part-
to-part variation. In an effort to better quantify the
drift of the MAX6070 core over time, Maxim has
evaluated 16 samples on two identical bench setups.
Sixteen MAX6070AAUT25+ samples were installed on a
pair of development boards. One board was set up in a
humidity and temperature controlled oven. The conditions
were set to 25°C and 40% relative humidity. The second
board was set up on the lab bench in the open air, where
humidity was measured to fluctuate between 18% and 51%.
the oven (on the lab bench). The swings in humidity are
Figure 4
apparent in
, with the output voltage drift primarily
tracking the humidity changes.
Maxim is studying the effects of drift and humidity on
multiple references beyond 1,000 hours. Contact the
Maxim technical support line or your local sales office for
details on the latest data.
The results of these experiments are detailed in Figure 4,
Figure 5, and Figure 6. The latest data shows the drift out
to 5,800 hours. The y axis is the drift, measured in parts
per million, between +50ppm and -50ppm. Figure 4 shows
the 16 parts on the lab bench in the open air. It is here the
effects of the humidity fluctuating between 18% and 51%
can be seen.
