MAX4239 Overview
The MAX4238/MAX4239 are low-noise, low-drift, ultrahigh precision amplifiers that offer near-zero DC offset and drift through the use of patented autocorrelating zeroing techniques. This method constantly measures and pensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise.
