Introduction

1.2 Description

The TPA701 MSOP audio power amplifier evaluation module is a complete,

low-power single-channel audio power amplifier. It consists of the TI TPA701

700-mWlow-voltage audiopower amplifierICin averysmall MSOPpackage,

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 TPA701 is replaced with the code TIABA.

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 pair of TPA701 MSOP evaluation modules 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,

andconnectsthemtoaversatilearrayofstandardaudioinputandoutputjacks

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.
