MAXIM INTEGRATED / ANALOG DEVICES MAX4239AUT+T Datasheet & Stock

The MAX4239AUT+T is an ultra low offset/drift, low noise, precision amplifier in 6 pin SOT-23 package. The high precision amplifier offers 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, temperature and the effect of 1/f noise. It features rail to rail outputs, operate from a single 2.7V to 5.5V supply and consume only 600μA. An active low shutdown mode decreases supply current to 0.1μA. Typical applications include thermocouples, strain gauges, electronic scales, medical instrumentation and instrumentation amplifiers.
