Follow the steps in this chapter to prepare the TPA741 MSOP audio amplifier
EVM for use. Using the TPA741 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 it can be wired directly into
existing circuits or equipment.
The platform switch and jumper settings shown in Table 2–1 are typical for the
TPA741 MSOP EVM. They cause the TPA741 amplifier IC on the EVM to shut
down when a plug is inserted into platform headphone jack J10.
