DESCRIPTIONThe 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.
