DESCRIPTION
The TPA6011A4 is a stereo audio power amplifier that
drives 2 W/channel of continuous RMS power into a 3-
load. Advanced dc volume control minimizes external
components and allows BTL (speaker) volume control
and SE (headphone) volume control. Notebook and
pocket PCs benefit from the integrated feature set that
minimizes external components without sacrificing
functionality.
To simplify design, the speaker volume level is adjusted
by applying a dc voltage to the VOLUME terminal.
Likewise, the delta between speaker volume and
headphone volume can be adjusted by applying a dc
voltage to the SEDIFF terminal. To avoid an unexpected
high volume level through the headphones, a third
terminal, SEMAX, limits the headphone volume level
when a dc voltage is applied. Finally, to ensure a smooth
transition between active and shutdown modes, a fade
mode ramps the volume up and down.
