DESCRIPTION

The TPA3003D2 is a 3-W (per channel) efficient,

Class-D audio amplifier for driving bridged-tied stereo

speakers. The TPA3003D2 can drive stereo speakers

as low as 8 Ω. The high efficiency of the TPA3003D2

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.
