 | Kit Overview
The TPA3123D2TPA3123D2 evaluation module (TPA3123D2EVMTPA3123D2EVM) consists of a single 25 W, class-D, stereo audio power amplifier complete with a small number of external components mounted on a circuit board that are used to directly drive speakers with an external analog audio source as the input.
The TPA3123D2TPA3123D2 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 TPA3123D2TPA3123D2 can drive stereo speakers as low as 4
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 noise in the speakers without additional circuitry.
