The MAX4063 is a differential-input microphone preampli-

fier optimized for high-performance, portable applica-

tions. The device features two selectable inputs,

differential outputs, adjustable gain, an integrated low-

noise bias source, and a low-power shutdown mode.

Two input paths provide both differential and single-

ended microphone sensing. The high-noise rejection of

the differential input is ideally suited to an internal micro-

phone where system noise and long-run PC board traces

can degrade low-level signals. The single-ended input

provides a simple connection to an external microphone.

The differential and single-ended inputs have indepen-

dent, adjustable gains that are set with a single external

resistor. Differential outputs provide a full-scale signal of

up to 6V

dynamic range of the amplified signal. A complete shut-

down mode reduces the supply current to only 0.3µA

and disables the microphone bias for the ultimate in

power savings.

The MAX4063 operates from 2.4V to 5.5V and is specified

over the extended -40°C to +85°C operating temperature

range. The MAX4063 is available in both 16-pin thin QFN

(4mm x 4mm x 0.8mm) and 14-pin TSSOP packages.
