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 4Ω. 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 36dB.
The patented start-up and shutdown sequences minimize pop noise in the speakers without additional circuitry.
