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
. 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.
