This section provides an overview of the Texas Instruments (TI) TPA2013D1 audio amplifier evaluation
module (TPA2013D1EVM). It includes a brief description of the module and a list of EVM specifications.

The TPA2013D1 is a 2.7-W Class-D amplifier with built-in boost converter. It drives up to 2.7 W (10% THD
+ N) into a 4-

speaker from low supply voltages.

The TPA2013D1 audio power amplifier evaluation module is a complete, stand-alone audio board. It
contains the TPA2013D1 QFN (RGP) Class-D audio power amplifier with an integrated boost converter.
All components and the evaluation module are Pb-Free.
