Introduction

1.2 Description

The TPA311 MSOP audio power amplifier evaluation module is a complete,

low-power single-channel audio power amplifier. It consists of the TI TPA311

350-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 TPA311 is replaced with the code TIAAB

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

evaluationplatform, or to be wired directlyintoexisting circuitsandequipment

when used stand-alone.

The platform has room for a pair of TPA311 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 auto-

matically provides power to the modules, interconnects them correctly, and

connectsthemtoaversatilearrayofstandardaudioinputandoutputjacksand

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.”
