TPA3123D2 Datasheet PDF - TI

●The TPA3123D2 is a 25-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 TPA3123D2 can drive stereo speakers as low as 4 . The efficiency of the TPA3123D2 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, 36 dB.

●The patented start-up and shut-down sequences minimize

●pop
