TPA6011A4
SLOS392A – FEBRUARY 2002 – REVISED JULY 2004
3-W STEREO AUDIO POWER AMPLIFIER
WITH ADVANCED DC VOLUME CONTROL
Advanced DC Volume Control With 2-dB
The TPA6011A4 is a stereo audio power amplifier
Steps
that drives 3 W/channel of continuous RMS power
From -40 dB to 20 dB
into a 3-
load. Advanced dc volume control
minimizes external components and allows BTL
– Fade Mode
(speaker) volume control and SE (headphone) vol-
– Maximum Volume Setting for SE Mode
ume control. Notebook and pocket PCs benefit from
– Adjustable SE Volume Control
the integrated feature set that minimizes external
Referenced to BTL Volume Control
components without sacrificing functionality.
3 W Into 3-
Speakers
To simplify design, the speaker volume level is
adjusted by applying a dc voltage to the VOLUME
Stereo Input MUX
terminal. Likewise, the delta between speaker volume
Differential Inputs
and headphone volume can be adjusted by applying
a dc voltage to the SEDIFF terminal. To avoid an
unexpected
high
volume
level
through
the
Notebook PC
headphones, a third terminal, SEMAX, limits the
LCD Monitors
headphone volume level when a dc voltage is ap-
plied. Finally, to ensure a smooth transition between
Pocket PC
active and shutdown modes, a fade mode ramps the
volume up and down.
