Introduction

1.2 Description

The TPA0253 audio power amplifier evaluation module is a complete 1-watt

mono audio power amplifier with stereo headphone drive. It consists of the TI

TPA0253 mono 1-W audio power amplifier IC along with a small number of

other parts mounted on a circuit board that measures approximately 2 1/4

inches by 1 1/2 inches (Figure 1–1).

Single in-line header pins extend from the underside of the module circuit

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

evaluationplatform,ortobewired directlyintoexistingcircuitsandequipment

when used stand-alone.

The platform has room for a single TPA0253 evaluation module and 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,

andconnectsthemtoaversatilearrayofstandardaudioinputandoutputjacks

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

hook up
