产品概述
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.
