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 pack-
age. These devices provide a 1/f noise voltage of only
4.8µV_P-P at an output voltage of 2.5V, with a temperature
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.
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.
