Quick Start

The steps in this chapter can be followed to quickly prepare the TPA0103 audio

amplifier EVM for use. Using the TPA0103 with the TI Plug-N-Play Audio

Amplifier Evaluation Platform is a quick and easy way to connect power, signal

and control inputs, and signal outputs to the EVM using standard connectors.

The audio amplifier evaluation module can also be used stand-alone by

making connections directly to the module pins, and it can be wired directly into

existing circuits or equipment.

The platform switch and jumper settings shown in Tables 2–1 and the

TPA0103 EVM jumper settings shown in Table 2–2 are typical for the TPA0103

EVM.
