The MAX4238/MAX4239 are low-noise, low-drift, ultra-

high precision amplifiers that offer near-zero DC offset

and drift through the use of autocorrelating zeroing tech-

niques. This method constantly measures and compen-

sates the input offset, eliminating drift over time and

temperature and the effect of 1/f noise. Both devices fea-

ture rail-to-rail outputs, operate from a single 2.7V to 5.5V

supply, and consume only 600µA. An active-low shut-

down mode decreases supply current to 0.1µA.

The MAX4238 is unity-gain stable with a gain-band-

width product of 1MHz, while the decompensated

MAX4239 is stable with A

6.5MHz. The MAX4238/MAX4239 are available in 8-pin

narrow SO, 6-pin TDFN and SOT23 packages.
