TheTPA301audiopoweramplifierevaluationmoduleisacomplete,low-pow-

er single-channel audio power amplifier. It consists of the TI TPA301 350-mW

low-voltage audio power amplifier IC along with a small number of other parts

mounted on a circuit board that is approximately one and a quarter inches

square (Figure 1–1).

Single in-line header pins are mounted to the underside of the module circuit

board to allow the EVM to be plugged into the TI plug-n-play audio amplifier

evaluationplatform, or to be wired directlyintoexisting circuitsandequipment

when used stand-alone.

The platform has room for a pair of TPA301 evaluation modules and is a

convenient vehicle for demonstrating TI’s audio power amplifier and related

evaluation modules. The EVMs simply plug into the platform, which auto-

matically provides power to the modules, interconnects them correctly, and

connectsthemtoaversatilearrayofstandardaudioinputandoutputjacksand

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 hook up.
