Operation
The quick start lists in this chapter contain steps that can be followed to quickly
prepare the TPA0211 mono audio amplifier EVM for use either with the TI
plug-n-play audio amplifier evaluation platform or for stand-alone operation.
Using the EVM with the TI evaluation platform is a quick and easy way to
connect power, signal and control inputs, and signal outputs to the EVM, using
standard connectors.
The platform switch and jumper settings shown in Table 2–1 are typical for the
TPA0211 EVM. They will cause the TPA0211 IC to switch to single-ended out-
put mode when a plug is inserted into platform headphone jack J10.

TPA0211 Mode X Hi Note 2 X
Notes: 1) X = Don’t care
2) Set S2 to ON when signal conditioning board is installed in U1; set S2
to OFF when no signal conditioning board is installed.
The audio amplifier evaluation module can also be used stand-alone by
making connections directly to the module pins, and it can be wired directly into
existing circuits or equipment. Stand-alone connection diagrams appear
below.
The chapter ends with a schematic and parts list for the EVM.
