Introduction
Theplug-n-playplatformhasroomforasingleTPA6017A2evaluationmodule
and is convenient for evaluating the TPA6017A2 device. The EVMs simply
plug into the platform, which provides power to the modules and connects
them to a versatile array of standard audio input and output jacks and
connectors.
There is nothing to build, nothing to solder, and nothing but the speakers
included with the platform to hook up.
