DESCRIPTION
The TPA3121D2 is a 15-W (per channel), efficient,
class-D audio power amplifier for driving stereo
speakers in a single-ended configuration or a mono
speaker in a bridge-tied-load configuration. The TPA3121D2 can drive stereo speakers as low as 4 Ω.
The efficiency of the TPA3121D2 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.
The patented start-up and shutdown sequences
minimize pop noise in the speakers without additional
circuitry.
