Differential Microphone Preamplifiers with

Internal Bias and Complete Shutdown

General Description

Features

♦ 2.4V to 5.5V Single-Supply Operation

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.

♦ Adjustable Gain or Fixed-Gain Options

♦ High PSRR (86dB at 1kHz)

♦ High CMRR (70dB at 1kHz)

♦ Low Input-Referred Noise

♦ Integrated Microphone Bias

♦ 750µA Supply Current

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.

♦ 0.3µA Shutdown Current

♦

4kV ꢀSꢁ Protection (AꢂUXIN)

♦ Rail-to-Rail Outputs

♦ THꢁ+N: 0.04% at 1kHz

♦ Available in Space-Saving Packages

8-Pin Thin QFN (MAU4060/MAU4061)

8-Pin µMAU (MAU4060/MAU4061)

10-Pin µMAU (MAU4062)

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

Typical Operating Circuit

(3mm x 3mm x 0.8mm) and 8-pin µMAX packages.

The MAX4062 is available in a 10-pin µMAX package.
