Product Summary
The MAX4238ASA+T is a low-noise, low-drift, ultrahigh precision amplifier that 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 and temperature and the effect of 1/f noise. The MAX4238ASA+T features rail-to-rail outputs, operates from a single 2.7V to 5.5V supply, and consume only 600μA. The applications of the MAX4238ATT+T include: Thermocouples, Strain Gauges, Electronic Scales, Medical Instrumentation, Instrumentation Amplifiers.
