TPA3106D1EVM: 40W x 1 @ 8Ω, 10 ~ 26V in, Class D

Summary

The TPA3106D1 evaluation module consists of a single 40 W, class-D, mono audio power amplifier; complete with a small number of external components mounted on a circuit board that can be used to directly drive speakers with an external analog audio source as the input.

The TPA3106D1 is a 40-W efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. The TPA3106D1 can drive stereo speakers as low as 4Ω. The high efficiency, ~92%, of the

TPA3106D1 eliminates the need for an external heatsink 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 outputs are fully protected against shorts to GND, VCC, and output-to-output shorts with an auto recovery feature and monitor output.
