DESCRIPTION

The TPA3004D2 is a 12-W (per channel) efficient,

Class-D audio amplifier for driving bridged-tied stereo

speakers. The TPA3004D2 can drive stereo speakers

as low as 4 Ω. The high efficiency of the TPA3004D2 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.
