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

into a 3-
load. Advanced dc volume control

minimizes external components and allows BTL

from
the

that
minimizes

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

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.
