MAX44250/MAX44251/MAX44252

20V, Ultra-Precision, Low-Noise Op Amps

General Description

Benefits and Features

The MAX44250/MAX44251/MAX44252 are 20V, ultra-

precision, low-noise, low-drift amplifiers that offer near-

zero DC offset and drift through the use of patented auto-

correlating zeroing techniques. This method constantly

measures and compensates the input offset, eliminating

drift over time and temperature and the effect of 1/f noise.

These single, dual, and quad devices feature rail-to-rail

outputs, operate from a single 2.7V to 20V supply or dual

1.ꢀ5V to 10V supplies and consume only 1.15mA

per channel, while providing 5.9nV/√Hz input-referred

voltage noise. The ICs are unity-gain stable with a gain-

bandwidth product of 10MHz.
