8/MAX719

General Description

Features

The MAX9718/MAX9719 differential input audio power

amplifiers are ideal for portable audio devices with

internal speakers. The differential input structure

improves noise rejection and provides common-mode

rejection. A bridge-tied load (BTL) architecture mini-

mizes external component count, while providing high-

quality, power audio amplification. The MAX9718 is a

single-channel amplifier while the MAX9719 is a dual-

channel amplifier for stereo systems. Both devices

deliver 1.4W continuous average power per channel to

a 4Ω load with less than 1% THD+N while operating

from a single +5V supply. The devices are available as

adjustable gain amplifiers or with internally fixed gains

of 0dB, 3dB, and 6dB to reduce component count.

o 2.7V to 5.5V Single-Supply Operation

o Very High -93dB PSRR at 217Hz

o 1.4W into 4Ω at 1% THD+N (per Channel)

o Differential Input

o Internal Fixed Gain to Reduce Component Count

o Adjustable Gain Option (MAX9718A/H/MAX9719A)

o 100nA Low-Power Shutdown Mode

o No Audible Clicks or Pops at Power-Up/Down

o Improved Performance Pin-Compatible Upgrade

to LM4895 (MAX9718D/G)

o 1.8V Logic Compatible

A shutdown input disables the bias generator and

amplifiers and reduces quiescent current consumption

to less than 100nA. The MAX9718 shutdown input can

be set as active high or active low. These devices fea-

ture Maxim’s comprehensive click-and-pop suppres-

sion circuitry that reduces audible clicks and pops

during startup and shutdown.
