Overview
MAX873/MAX875/MAX876 19-0038; Rev 3; 6/07 Low-Power, Low-Drift, +2.
5V/+5V/+10V Precision Voltage References General Description 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.
