1.2 Description
The TPA0202 Stereo 2-W Audio Power Amplifier Evaluation Module is a
complete, 2-Watt per channel stereo audio power amplifier. It consists of the
TI TPA0202 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
Evaluation Platform, or to be wired directly into existing circuits and equipment
when used stand-alone.
The platform has room for a single TPA0202 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,
and connects them to a versatile array of standard audio input and output jacks
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.”
