Introduction
1.2 Description
The TPA032D03 mono class-D audio power amplifier evaluation module is a
complete, 10-W mono audio power amplifier. It consists of the TI TPA032D03
mono class-D audio power amplifier IC along with a small number of other
parts mounted on a circuit board that measures approximately 2 inches by
1 inches (Figure 1–1 and 1–2).
