Quick Start
The steps in this chapter can be followed to quickly prepare the TPA122 MSOP
audio amplifier EVM for use. Using the TPA122 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
TPA122 MSOP EVM and will cause the TPA122 IC to shut down/mute when
a plug is removed from platform headphone jack J10.
