General Description
The MAX4060/MAX4061/MAX4062 are differential-input
microphone preamplifiers optimized for notebook and
PDA audio systems. These devices feature adjustable
gain with excellent power-supply rejection and com-
mon-mode rejection ratios, making them ideal for low-
noise applications in portable audio systems.
The MAX4060/MAX4062 are capable of switching their
output between the differential input and a single-
ended auxiliary microphone amplifier input. In addition,
the MAX4060/MAX4062 have a low-noise microphone
bias generator. The differential gain of the
MAX4061/MAX4062 is set with a single resistor. The
MAX4060 has a fixed gain of 10V/V and is PC99/2001
compliant. The MAX4061 includes a complete shut-
down mode. In shutdown, the supply current is
reduced to 0.3μA and the current to the microphone
bias is cut off for ultimate power savings.
The MAX4060 operates from a 4.5V to 5.5V single sup-
ply and the MAX4061/MAX4062 operate from 2.4V to
5.5V. All devices are specified over the extended oper-
ating temperature range, -40°C to +85°C. The
MAX4060/MAX4061 are available in tiny 8-pin thin QFN
(3mm x 3mm x 0.8mm) and 8-pin μMAX packages. The
MAX4062 is available in a 10-pin μMAX package.
