DESCRIPTION

The TPA3002D2 is a 9-W (per channel) efficient, Class-D

audio amplifier for driving bridged-tied stereo speakers.

The TPA3002D2 can drive stereo speakers as low as 8 Ω.

The high efficiency of the TPA3002D2 eliminates the need

for external heatsinks when playing music.

Stereo speaker volume is controlled with a dc voltage

applied to the volume control terminal offering a range of

gain from –40 dB to 36 dB. Line outputs, for driving external

headphone amplifier inputs, are also dc voltage controlled

with a range of gain from –56 dB to 20 dB.

An integrated 5-V regulated supply is provided for

powering an external headphone amplifier.
