1.2 Description
The TPA005D02 Class D Stereo Audio Power Amplifier Evaluation Module is
a complete, 2-Watt per channel stereo audio power amplifier. It consists of the
TI TPA005D02 Class D Stereo 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 3/4 inches (Figure 1–1).

Shutdown
Single in-line header pins extend from the underside of the module circuit
board to allow the EVM to either be plugged into the TI Plug-N-Play Audio Am-
plifier Evaluation Platform, or to be wired directly into existing circuits and
equipment when used stand-alone.
The platform has room for a single TPA005D02 class D 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.
