The MAX4465 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 an ultra-small package. The MAX4465 are unity-gain stable and deliver a 200kHz gain bandwidth from only 24µA of supply current. In addition these amplifiers feature rail-to-rail outputs, high A_VOL, plus excellent power-supply rejection and common-mode rejection ratios for operation in noisy environments.

The single MAX4465 are offered in the ultra-small 5-pin SC70 package.
