1.3 Description
1.4 TPA2031D1EVM Specifications
www.ti.com Introduction
The TPA2031D1 audio power amplifier evaluation module is a complete, low-power single-channel audio
power amplifier. It consists of the TI TPA2031D1 2.5-W low-voltage Class-D audio power amplifier IC in a
very small NanoFree™ WCSP package, along with a small number of other parts mounted on a circuit
board that is approximately 1.25-inches square.
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, which has room for a pair of TPA2031D1 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
connect.
