This section provides an overview of the Texas Instruments (TI) TPA2014D1 audio amplifier evaluation
module (TPA2014D1EVM). It includes a brief description of the module and a list of EVM specifications.
The TPA2014D1 is a 1.5 W, Class-D amplifier with built-in boost converter. It drives up to 1.5 W (10%
THD + N) into a 8- Ω speaker from low supply voltages.
The TPA2014D1 audio power amplifier evaluation module(EVM) is a complete, stand-alone audio board. It
contains the TPA2014D1 QFN (RGP) Class-D audio power amplifier with an integrated boost converter.
All components and the EVM are Pb-free.
