Quick Start List for Platform
Follow these steps when using the TPA0212 EVM with the TI plug-n-play audio

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 TPA0212 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 (U1).
4) Set control signal Polarity jumper JP8 to
Hi.
5) Set jumper JP6 to select the
Mode control input (causes the TPA0212 to
switch to the single-ended output mode if a plug is inserted into platform
headphone jack J10).
6) If the headphone jack (J10) output will be used, set headphone source
switch S3 to U2– U4.

or
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).
