Quick Start

Quick Start

The steps in this chapter can be followed to quickly prepare the TPA0202 audio
amplifier EVM for use. Using the TPA0202 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.
However, the audio amplifier evaluation module can be used stand-alone by
making connections directly to the module pins, and can be wired directly into
existing circuits or equipment.

The platform switch and jumper settings shown in Table 2–1 are typical for the
TPA0202 EVM and will cause the TPA0202 to switch to single-ended output
mode when a plug is inserted into platform headphone jack J10.
