Quick Start List for Platform
Operation
Figure 2. Quick Start Platform Map
Follow these steps when using the TPA6205A1DRB EVM with the TI plug-n-play audio amplifier
evaluation platform (see the platform user's guide,
, for additional details). Numbered callouts for
selected steps are shown in
.
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 TPA6205A1DRB module in platform sockets U3 and U4 for stereo operation (or a module in
either U3 or U4 for single channel operation), 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 (which causes the TPA6205A1DRB to shut down if a
plug is inserted into platform headphone jack J10).
