Follow the steps in this chapter to quickly prepare the TPA321 audio amplifier
EVM for use. The TPA321 and the TI plug-n-play audio amplifier evaluation
platform provide 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
TPA321 EVM. These settings cause the TPA321 to mute when a plug is in-
serted into platform headphone jack J10.
