2.2 Quick Start List for Platform
Follow these steps when using the TPA2008D2 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 2–2, and details appear in Chapter 3.
- 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 TPA2008D2 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 Lo.
5) Set jumper JP6 to select the Mute control input (causes the TPA2008D2
to shut down if a plug is inserted into platform headphone jack J10).
6) If a headphone amplifier will be installed in U5, set the headphone source
switch S3 to U5.

2) Set S2 to ON when signal conditioning board is installed in U1; set S2
to OFF when no signal conditioning board is installed.

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.
- Inputs and outputs
8) Ensure that the audio signal source level is set to minimum.
9) Connect the audio source to left and right RCA phono jacks J3 and J5 or
stereo miniature phone jack J4.
