3-W STEREO AUDIO POWER AMPLIFIER

WITH ADVANCED DC VOLUME CONTROL

Check for Samples :TPA6012A4

FEATURES

DESCRIPTION

•

Advanced 32 Steps DC Volume Control

–

Steps From –40 dB to 18 dB

Fade Mode

The TPA6012A4 is a stereo audio power amplifier

that drives 3 W/channel of continuous RMS power

into

a 3-Ω load. Advanced dc volume control

–85-dB Mute Mode

minimizes external components and allows BTL

(speaker) volume control and SE (headphone)

volume control. LCD monitors and notebook benefit

from the integrated feature set that minimizes

external components without sacrificing functionality.

•

3 W Into 3-Ω Speakers

Differential Inputs

Headphone Mode

Pin-to-Pin Compatible With TPA6011A4 and

TPA6013A4

To simplify design, the speaker volume level is

adjusted by applying a dc voltage to the VOLUME

terminal. To ensure a smooth transition between

active and shutdown modes, a fade mode ramps the

volume up and down.
