TPA005D12 Class-D EVM Specifications
1-4
Introduction
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.
