2-1 Quick Start
Quick Start
Follow the steps in this chapter to quickly prepare the TPA721 MSOP audio
amplifier EVM for use. Using the TPA721 MSOP EVM 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
TPA721 MSOP EVM. They will cause the TPA721 amplifier IC on the EVM to
shut down when a plug is inserted into platform headphone jack J10.
