3-W STEREO AUDIO POWER AMPLIFIER

WITH ADVANCED DC VOLUME CONTROL

Check for Samples :TPA6013A4

FEATURES

DESCRIPTION

• Advanced 32-Steps DC Volume Control

– Steps from –40 to 18 dB

The TPA6013A4 is a stereo audio power amplifier

that drives 3 W/channel of continuous RMS power

– Fade Mode

into a 3-Ω load. Advanced dc volume control

– Maximum Volume Setting for SE Mode

minimizes external components and allows BTL

– Adjustable SE Volume Control

(speaker) volume control and SE (headphone)

Referenced to BTL Volume Control volume control. Notebook and pocket PCs benefit

from the integrated feature set that minimizes

• 3 W Into 3-Ω Speakers

external components without sacrificing functionality.

• Stereo Input MUX

To simplify design, the speaker volume level is

• Headphone Mode

adjusted by applying a dc voltage to the VOLUME

• Pin-to-pin compatible with TPA6011A4 and

terminal. Likewise, the delta between speaker volume

TPA6012A4

and headphone volume can be adjusted by applying

a dc voltage to the SEDIFF terminal. To avoid an

• 24-pin PowerPAD™ Package (PWP)

unexpected high volume level through the

headphones, a third terminal, SEMAX, limits the

APPLICATIONS

headphone volume level when a dc voltage is

• Notebook PC

applied. Finally, to ensure a smooth transition

• LCD Monitors

between active and shutdown modes, a fade mode

• Pocket PC

ramps the volume up and down.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
