Texas InstrumentsTPA3116D2EVM放大器集成电路开发电路板和套件

The TPA3116D2 evaluation module consists of a single 50-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 or micro inductors. The EVM can also be configured as a 100-W, Class-D mono audio power amplifier.

Designers can quickly evaluate the sound quality and verify specifications in their application with the TPA3116D2EVM. In addition, the TPA3116D2EVM User's Guide contains the schematic, layout and bill of materials for a reference design
