1 Introduction
This section provides an overview of the Texas Instruments (TI) TPA2025D1 audio power amplifier
evaluation module (EVM). It includes a brief description of the module and a list of specifications.
1.1 Description
The TPA2025D1 is a high-efficiency, class-D, audio power amplifier and an integrated boost converter. It
drives up to 2 W into a 4-Ω speaker from low supply voltages.
The TPA2025D1 audio power amplifier EVM is a complete, stand-alone audio amplifier. It contains the
TPA2025D1 WCSP (YZG) Class-D audio power amplifier with an integrated boost converter. All
components and the EVM are Pb-Free.
