General Description
The MAX4238/MAX4239 are low-noise, low-drift, ultra-
high precision 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. Both
devices feature rail-to-rail outputs, operate from a single
2.7V to 5.5V supply, and consume only 600A. An active-
low shutdown mode decreases supply current to 0.1A.
The MAX4238 is unity-gain stable with a gain-band-
width product of 1MHz, while the decompensated
MAX4239 is stable with AV
≥ 10V/V and a GBWP of
6.5MHz. The MAX4238/MAX4239 are available in 8-pin
narrow SO, 6-pin TDFN and SOT23 packages.
