TPA6030A4 www.ti.com SLOS395B -DECEMBER 2002 -REVISED JANUARY 2005 3-W STEREO AUDIO POWER AMPLIFIER
WITH ADVANCED DC VOLUME CONTROL
FEATURES DESCRIPTION
The TPA6030A4 is designed to drive 3 W into 16-Ω
speakers using a surface-mount package without the need
for an external heatsink. These features make it ideal for
15I-17I LCD monitors, small multimedia speakers, and
notebook computers. D 3 W Into 16 Ω From 12-V Supply
D Volume Control for Speakers (BTL) and
Headphones (SE) D Differential Inputs To simplify system design, the speaker volume level is
adjusted by applying a dc voltage to the VOLUME
terminal. 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. Integrated depop circuitry
and the fully differential design minimize pops, clicks, and
unwanted noise to provide a high level of audio
performance. D Depop Circuitry
