Texas Instruments 1.3 TPA005D12 Class-DEVM Specifications, 1.3.1Maximum, Typical, Introduction

TPA005D12 Class-D EVM Specifications

Single in-line header pins extend from the underside of the module circuit board to allow the EVM to either 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 TPA005D12 class-D evaluation module and is a convenient vehicle for demonstrating TI's audio power amplifier and related evaluation modules. The EVM simply plugs 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.
