General Description

The MAX4465–MAX4469 are micropower op amps optimized for use as microphone preamplifiers. They provide the ideal combination of an optimized gain bandwidth product vs. supply current, and low voltage operation in ultra-small packages. The MAX4465/MAX4467/MAX4469 are unity-gain stable and deliver a 200kHz gain bandwidth from only 24µA of supply current. The MAX4466/MAX4468 are decompensated for a minimum stable gain of +5V/V and provide a 600kHzgain bandwidth product. In addition, these amplifiers feature Rail-to-Rail® outputs, high AVOL, plus excellent power-supply rejection and common-mode rejection ratios for operation in noisy environments.
