Introduction
1.2 Description
The TPA6102A2 audio power amplifier evaluation module is a complete,
low-power stereo audio power amplifier for high-fidelity line-level output,
headphone, and small speaker applications. It consists of the TI TPA6102A2
50-mW stereo 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 (see Figure 1–1).

Due to the very small size of the MSOP IC package, the standard part number TPA6102A2 is
replaced with the code TIAJN.
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 has room for a single TPA6102A2 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.
