Operation

The steps in this chapter can be followed to quickly prepare the TPA2008D2

stereo filter-free class-D audio amplifier EVM for use. Using the TPA2008D2

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

TPA2008D2 EVM and causes the TPA2008D2 to shut down when a plug is in-

serted into platform headphone jack J10.
