The MAX44250AUA+ is a 20V, ultra precision, low noise operational amplifier (op-amp) in 8 pin μMAX package. This single amplifier offers near zero DC offset and drifts through the use of patented auto correlating zeroing techniques. This method constantly measures and compensates the input offset eliminates drift over time, temperature and the effect of 1/f noise. It features rail to rail output to operate from a single supply or dual supply and consume only 1.15mA per channel by providing 5.9nV/√Hz input referred voltage noise and IC is unity-gain stable with a gain bandwidth product of 10MHz. It is ideally suited for applications requiring ultra-low noise and DC precision such as interfacing with pressure sensors, strain gauges, precision weight scales and medical instrumentation.
