Texas Instruments  TPA3118D2EVM

The TPA3118D2 evaluation module showcases TI’s 30-W Stereo Analog Input Class-D Audio Amplifier 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 evaluation module can also be configured as a 60-W, Class-D mono audio amplifier in PBTL mode. TPA3118D2 requires no external heatsink as its pad-down package allows a PCB plane to be used as heatsink.

System designers can quickly evaluate TPA3118D2’s sound quality and verify system specifications with the TPA3118D2EVM evaluation module. The TPA3118D2EVM User's Guide contains the schematic, layout and bill of materials for a reference design.
