Power-Up
Ensure that required connections and configurations have been checked. The TPA3220EVM board can
now be powered on.
1. Enable the power supply from 12 V to 30 V and ensure that LED D5 illuminates. LEDs D2 and D4
should not be illuminated.
2. Bring the EVM out of RESET state by switching RESET (S1) to NORMAL. You should see the FAULT
LED (D4) blink once quickly, then remain unilluminated.
3. Bring the EVM out of MUTE state by switching MUTE (S2) to NORMAL.
4. Note that the EVM does not have volume control, configure your analog input for a reasonable audio
level before beginning audio playback.
5. Enable audio input playback and the EVM should begin driving audio out of the left and right speakers.
If resistor loads are used for testing instead of speakers, they will now be energized.
