Introduction
1.2 Description
The TPA0211 mono audio power amplifier evaluation module is a complete
single-channel audio power amplifier. It consists of the TI TPA0211 2-W mono
audio power amplifier IC in a very small MSOP package, along with a small
number of other parts mounted on a circuit board that is approximately one and
a quarter inches square (Figure 1–1).

Due to the very small size of the MSOP IC package, the standard part number TPA0211 is replaced with the code TIAEG
Single in-line header pins are mounted to 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, with room for a pair of TPA0211 evaluation modules, 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.
