Introduction

1.2 Description

The TPA751 MSOP Audio Power Amplifier Evaluation Module is a complete,

low-power single-channel audio power amplifier. It consists of the TI TPA751

700-mW low-voltage 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 TPA751 is

replaced with the code TIATC.

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, with room for a pair of TPA751 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.
