Helping to increase average speaker volume levels

Audio Power Amplifier with Built-in AGC AN12972A

Overview

Unit : mm

Increasing volume settings when using small speakers

results in distortion as the output signal distorts at high

gain settings. The AN12972A audio power amplifier

features built-in automatic gain control (AGC) circuitry

to minimize distortion by decreasing too high an input

gain level. Using a low-noise amp minimizes noise even

when the speaker is placed close to an ear.

Features

z Built-in AGC circuitry if an input level is too high, the

AGC is activated to minimize distortion, raising the

overall volume level and reducing noise.

z Low noise amplifier.

z Input circuit format accommodates different input

signals (mixing possible)

z Standby and speaker mute functions.

z Small package.

QFN016-P-0304B

z Cellular phones, PDAs and other mobile equipment
