2.2 Quick Start List for Platform
Follow these steps when using the TPA102 MSOP EVM with the TI
-shown in Figure
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 TPA102 MSOP module in platform socket U5, 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 JP7 to Lo.
5)Set Hp source switch S3 to U5 to route the output signal to the headphone Jack (J10).

2)Set S2 to ON when signal conditioning board is installed in U1; set S2
-to OFF when no signal conditioning board is installed.
Power supply
6) Select and connect the power supply:
a)Connect an external regulated power supply set to a voltage between 2.5 V and 5.5 V to platform VDD power input connector J6, taking care
to observe marked polarity, | or |
b)Install a
-appropriate power input (see platform user’s guide).
Inputs and outputs
7)Ensure that signal source level is set to minimum.
