Datasheet Analog Devices MAX875

19-0038; Rev 3; 6/07 Low-Power, Low-Drift, +2.5V/+5V/+10V
Precision Voltage References
The MAX873/MAX875/MAX876 precision 2.5V, 5V, and
10V references offer excellent accuracy and very low
power consumption. Extremely low temperature drift
combined with excellent line and load regulation permit
stable operation over a wide range of electrical and environmental conditions. Operation for the MAX873 is guaranteed with a +4.5V supply, making the part ideal in
systems running from a +5V ±10% supply. Low 10Hz to
1kHz noise—typically 3.8µVRMS, 9µVRMS, and 18µVRMS,
respectively, for the MAX873, MAX875, MAX876—make
the parts suitable for 12-bit data-acquisition systems.
A TRIM pin facilitates adjustment of the reference voltage
over a ±6% range, using only a 100kΩ potentiometer. A
voltage output proportional to temperature provides a
source for temperature compensation circuits, temperature warning circuits, and other applications. Features
