The TPA3123D2EVM is a TPA3123D2 evaluation module consists of a single 25W, 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 TPA3123D2 can drive stereo speakers as low as 4R . 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 20dB, 26dB, 32dB, 36dB. The patented start up and shut down sequences minimize pop noise in the speakers without additional circuitry.
