... Ultra-Precision, Low-Noise Op Amps General Description The MAX44251/MAX44252 are 20V, ultra-precision, low- noise, low-drift amplifiers that 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. These dual and quad devices feature rail-to-rail outputs, oper- ate from a single 2 ...
