12-W/Ch Into an 8-
Load From 15-V Supply
Efficient, Class-D Operation Eliminates
The TPA3004D2 is a 12-W (per channel) efficient,
Class-D audio amplifier for driving bridged-tied stereo
Heatsinks and Reduces Power Supply
speakers. The TPA3004D2 can drive stereo speakers
Requirements
as low as 4
. The high efficiency of the TPA3004D2
32-Step DC Volume Control From -40 dB to
eliminates the need for external heatsinks when
36 dB
playing music.
Line Outputs For External Headphone
Stereo speaker volume is controlled with a dc voltage
Amplifier With Volume Control
applied to the volume control terminal offering a
Regulated 5-V Supply Output for Powering
range of gain from -40 dB to 36 dB. Line outputs, for
