1.1 Description

The TPA6017A2 audio power amplifier evaluation module is a 2-watt per

channel class-AB stereo audio power amplifier complete with a small number

of external components mounted on a circuit board that measures

approximately 2-1/4 inches by 1-1/2 inches (Figure 1–1 and Figure 1–2).

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.
