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, and

consume only 1.15mA per channel, while providing

5.9nV/√Hz input- referred voltage noise. The ICs are uni-

ty-gain stable with a gain-bandwidth product of 10MHz.

S High Accuracy Enables Precision Signal Chain

0.1Hz to 10Hz, the ICs are ideally suited for applications

requiring ultra-low noise and DC precision such as inter-

facing with pressure sensors, strain gauges, precision

weight scales, and medical instrumentation.
