2.1 Quick Start List for Plug-n-Play Platform
Follow these steps when using the TPA6017A2 EVM with the TI plug-n-play
audio amplifier evaluation platform (see the platform user’s guide, literature
number SLOU011, for additional details). Numbered callouts for selected
steps are shown in Figure 2–1.

Platform Preparations
1) Ensure that all external power sources are set to OFF and that the
platform power switch S1 is set to OFF.
2) Install a TPA6017A2 module in platform socket U2, taking care to align
the module pins correctly.
3) Use switch S2 to select or bypass the signal conditioning EVM
installed in U1. If no EVM is installed in U1, set this switch to OFF.
4) Set control signal polarity jumper JP8 to Lo.
5) Set jumper JP6 to select the Mute control input (this causes the
TPA6017A2 to shut down if a plug is inserted into platform headphone
jack J10).
6) If a headphone amplifier will be installed in U5, set headphone source
switch S3 to U5.

b) Install a voltage regulator EVM (SLVP097 or equiv.) in platform
socket U6. Connect a 7-V–12-V power source to a platform V
CC
power input J1 or J2 and jumper the appropriate power input (see
platform user’s guide). If using J1, J2, or B1, set S1 to ON to
supply power to the EVM.
