Introduction
1.2 Description
The TPA0152 stereo 2-W audio power amplifier evaluation module is a
complete, 2-Watt per channel stereo audio power amplifier. It consists of the
TI TPA0152 stereo 2-W audio power amplifier IC along with a small number
of other parts mounted on a circuit board that measures approximately 2 ¼
inches by 1 ½ 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 TPA0152 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.
