Description

The TPA6110A2 MSOP 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
TPA6110A2 150-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 (Figure 1–1).

† Due to the very small size of the MSOP IC package, the standard part number TPA6110A2 is

replaced with the code TIAIZ.

Single in-line header pins are mounted to the underside of the module circuit
board; these pins 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 TPA6110A2 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.
