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 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 600µA. An active-low shutdown mode decreases supply current to 0.1µA.

The MAX4238 is unity-gain stable with a gain-bandwidth 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.

Product Detail

The MAX4238 evaluation kit (EV kit) provides a proven design to evaluate the MAX4238 precision, low-noise, low-drift dual-operational amplifier in an 8-pin µMAX® package. The EV kit circuit is preconfigured as noninverting amplifiers, but can be adapted to other topologies by changing a few components.

The EV kit comes with a MAX4238AUA+ installed.
