Description for the TPA2031D1EVM
The TPA2031D1 audio power amplifier evaluation module is a complete, low-power single-channel audio power amplifier. It consists of the TI TPA2031D1 2.5-W low-voltage Class-D audio power amplifier IC in a very small NanoFree™ WCSP package, along with a small number of other parts mounted on a circuit board that is approximately 1.25-inches square.
Single in-line header pins are mounted to the underside of the module circuit board. These pins allow the EVM to be plugged into the TI Plug-N-Play audio-amplifier evaluation platform, or to be wired directly into existing circuits and equipment when used stand-alone.
The platform, which has room for a pair of TPA2031D1 evaluation modules, is a convenient vehicle for demonstrating TI's audio power amplifier and related evaluation modules. The EVMs simply plug into the platform, which automatically provides power to the modules, interconnects them correctly, and connects them to a versatile array of standard audio input and output jacks and connectors. Easy-to-use configuration controls allow the platform and EVMs to quickly model many possible end-equipment configurations.
There is nothing to build, nothing to solder, and nothing but the speakers included with the platform to connect.
