MAX4060/MAX4061/

MAX4062

Differential Microphone Preamplifiers with

Internal Bias and Complete Shutdown

General Description

Features

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 common-

mode rejection ratios, making them ideal for lownoise

applications in portable audio systems.

● 2.4V to 5.5V Single-Supply Operation

● 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 shutdown 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 ESD Protection (AUX_IN)

● Rail-to-Rail Outputs

● THD+N: 0.04% at 1kHz

● Available in Space-Saving Packages

• 8-Pin TDFN (MAX4060/MAX4061)

• 8-Pin μMAX (MAX4060/MAX4061)

• 10-Pin μMAX (MAX4062)

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 operat-

ing temperature range, -40°C to +85°C. The MAX4060/

MAX4061 are available in tiny 8-pin TDFN (3mm x 3mm
