DESCRIPTION

The TPA3122D2 is a 15-W (per channel) efficient,

Class-D audio power amplifier for driving stereo single ended speakers or mono bridge tied load. The

TPA3122D2 can drive stereo speakers as low as 4Ω.

The efficiency of the TPA3122D2 eliminates the need

for an external heat sink when playing music.

The gain of the amplifier is controlled by two gain

select pins. The gain selections are 20, 26, 32, and

36 dB.
