The TPA3125D2 is a 10-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 TPA3125D2 can drive stereo speakers as low as 4 Ω. The efficiency of the TPA3125D2 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.

The thru-hole package allows placement on single-sided printed circuit boards.

TPA3125D2EVM — TPA3125D2 評估模組 (EVM)

The TPA3125D2 evaluation module (EVM) consists of a single 10 W, class-D, stereo audio power amplifier, complete with a small number of external components mounted on a circuit board. The EVM can be used to directly drive speakers with an external analog audio source as the input.
