Maxim Integrated MAX4238 Ultra-High Precision Amplifiers offer near-zero DC offset and drift through the use of patented autocorrelating zeroing techniques. This method constantly measures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise. MAX4238 precision amplifiers feature rail-to-rail outputs, operate from a single 2.7V to 5.5V suppler, and consume only 600µA, and an active-low shutdown mode decreases supply current to 0.1µA. The MAX4238 is unity-gain stable with gain-bandwidth product of 1MHz. These Maxim Integrated amplifiers are optimized for thermocouples, strain gauges, electronic scales, medical instrumentation, and instrumentation amplifiers.
