Stereo 3W Audio Power Amplifiers with

Headphone Drive and Input Mux

General Description

Features

The MAX9760–MAX9763 family combines a stereo or

mono 3W bridge-tied load (BTL) audio power amplifier,

stereo single-ended headphone amplifier, headphone

sensing, and a 2:1 input multiplexer all in a tiny 28-pin

thin QFN package. These devices operate from a sin-

gle 4.5V to 5.5V supply and feature an industry-leading

100dB PSRR, allowing these devices to operate from

noisy supplies without the addition of a linear regulator.

An ultra-low 0.002% THD+N ensures clean, low-distor-

tion amplification of the audio signal. Patented click-

and-pop suppression eliminates audible transients on

power and shutdown cycles. Power-saving features

ꢀ Industry-Leading, Ultra-High 100dB PSRR

ꢀ PC99/01 Compliant

ꢀ 3W BTL Stereo Speaker Amplifier

ꢀ 200mW Stereo Headphone Amplifier

ꢀ Low 0.002% THD+N

ꢀ Patented Click-and-Pop Suppression

ꢀ ESD-Protected Outputs

ꢀ Low Quiescent Current: 13mA

ꢀ Low-Power Shutdown Mode: 10µA

ꢀ MUTE Function

include low 4mV V

(minimizes DC current drain

through the speakers), low 13mA supply current, and a

10µA shutdown mode. A MUTE function allows the out-

puts to be quickly enabled or disabled.

ꢀ Headphone Sense Input

ꢀ Stereo 2:1 Input Multiplexer

A headphone sense input detects the presence of a

headphone jack and automatically configures the

amplifiers for either speaker or headphone mode. In

speaker mode, the amplifiers can deliver up to 3W of

continuous average power into a 3Ω load. In head-

phone mode, the amplifier can deliver up to 200mW of

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

the amplifiers is externally set, allowing maximum flexi-

bility in optimizing output levels for a given load. The

amplifiers also feature a 2:1 input multiplexer, allowing

multiple audio sources to be selected. The multiplexer

can also be used to compensate for limitations in the

frequency response of the loud speakers by selecting

an external equalizer network. The various functions are

controlled by either an I²C-compatible or simple parallel

control interface.

Simplified Block Diagram

The MAX9760–MAX9763 are available in either a ther-

mally efficient 28-pin thin QFN package (5mm ✕ 5mm ✕

0.8mm) or a TSSOP-EP package. All devices have ther-

mal overload protection (OVP) and are specified over

the extended -40°C to +85°C temperature range.
