The MAX4238ASA+ is a low-noise, low-drift, Ultra-high Precision Amplifier 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. Both devices feature rail-to-rail outputs, operate from a single 2.7 to 5.5V supply and consume only 600μA. An active-low shutdown mode decreases supply current to 0.1μA. The MAX4238 is unity-gain stable with a gain-bandwidth product of 1MHz.
