2.2 Quick Start List for Platform
Follow these steps when using the TPA032D03 class-D EVM with the TI
plug-n-play audio amplifier evaluation platform (see the platform user's guide,
SLOU011, for additional details). Numbered callouts for selected steps are
shown in Figure 2–1 and details appear in Chapter 3.
Platform Preparations
1) Ensure that all external power sources and platform power switch S1 are
2) Install a TPA032D03 module in platform socket U2, taking care to align the
