Texas InstrumentsTPA3118D2EVMKit e schede di sviluppo IC amplificatore

The TPA3118D2 evaluation module consists of a single 30-W, Class-D, stereo audio power amplifier complete with a small number of external components mounted on a circuit board that can be used to directly drive a speaker with an external analog audio source as the input. The EVM’s default output filter configuration supports LC filter operation, but can easily be configured to support filter-free operation. The EVM can also be configured as a 60-W, Class-D mono audio power amplifier.

Designers can quickly evaluate the sound quality and verify specifications in their application with the TPA3118D2EVM.
