750mW Audio Amplifiers with Headphone Amp,

Microphone Preamp, and Input Mux

General Description

Features

♦ 750mW BTL Stereo Speaker Amplifier

The MAX9765/MAX9766/MAX9767 family combines

speaker, headphone, and microphone amplifiers, all in

a small thin QFN package. The MAX9765 is targeted at

stereo speaker playback applications and includes a

stereo bridge-tied load (BTL) speaker amp, stereo

headphone amp, single-ended output mic amp, input

♦ 65mW Stereo Headphone Amplifier

♦ 2.7V to 5.5V Single-Supply Operation

♦ Click-and-Pop Suppression

♦ Low 0.003% THD+N

MUX, and I C control. The MAX9766 is targeted at

♦ Low Quiescent Current: 13mA

♦ Low-Power Shutdown Mode: 5µA

♦ MUTE Function

mono speaker playback applications and includes a

mono BTL speaker amp, stereo headphone amp, differ-

ential output mic amp, input MUX, and I C control. The

MAX9767 is targeted at applications that do not require

a headphone amp and includes a stereo BTL speaker

amp, differential output mic amp, and parallel control.

These devices operate from a single 2.7V to 5.5V supply.

A high 95dB PSRR allows these devices to operate from

noisy supplies without additional power conditioning. An

ultra-low 0.003% THD+N ensures clean, low distortion

amplification of the audio signal. Click-and-pop suppres-

sion eliminates audible transients on power and shut-

down cycles.

♦ Headphone Sense Input

♦ Stereo 2:1 Input Multiplexer

♦ Optional 2-Wire, I²C-Compatible, or Parallel

Interface

♦ Small 32-Pin Thin QFN (5mm ✕ 5mm ✕ 0.8mm)

TEMP RANGE

In speaker mode, the amplifiers can deliver up to

750mW of continuous average power into a 4Ω load. In

headphone mode, the amplifier can deliver up to 65mW

of continuous average power into a 16Ω load. The gain

of the amplifiers is externally set, allowing maximum

flexibility in optimizing output levels for a given load.

The MAX9765/MAX9766 also feature a 2:1 input multi-

plexer, allowing multiple audio sources to be selected.

The various functions are controlled by either an I²C-

compatible (MAX9765/MAX9766) or simple parallel

control interface (MAX9767).

All devices include two low-noise microphone pre-

amps, a differential amp for internal microphones, and

a single-ended amplifier for additional external micro-

phones. A microphone bias output is provided, reduc-

ing external component count.
