The MAX4465–MAX4469 are micropower op amps opti-
mized for use as microphone preamplifiers. They pro-
vide 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 cur-
rent. The MAX4466/MAX4468 are decompensated for a
minimum stable gain of +5V/V and provide a 600kHz
gain bandwidth product. In addition, these amplifiers
feature Rail-to-Rail
power-supply rejection and common-mode rejection
ratios for operation in noisy environments.
The MAX4467/MAX4468 include a complete shutdown
mode. In shutdown, the amplifiers’ supply current is
reduced to 5nA and the bias current to the external
microphone is cut off for ultimate power savings. The
single MAX4465/MAX4466 are offered in the ultra-small
5-pin SC70 package, while the single with shutdown
MAX4467/MAX4468 and dual MAX4469 are available in
the space-saving 8-pin SOT23 package.
