1. Ensure the power supply is OFF. Connect the power supply positive terminal to J1 PVDD (red) and negative terminal to J1 GND (black). 2. Connect the left channel speaker, power resistor load (3–8 Ω) to the TPA3223EVM positive output terminal (J9 OUT1+ (red)) and other side of the speaker, power resistor to the TPA3223EVM negative output terminal (J9 OUT1–... - Page 6 5. Enable audio input playback and the EVM begins driving audio out of the left and right speakers. If resistor loads are used for testing instead of speakers, then the load will now be energized.

Page 11: Modulation Modes (Ad Mode And Head Mode)
3.3 Modulation Modes (AD Mode and HEAD Mode) The TPA3223EVM supports both AD modulation as well as HEAD modulation. In AD mode, each of the two half-bridge outputs are continuously switching. AD mode is the default mode for the TPA3223EVM. The EVM also supports HEAD mode modulation. -

PVDD voltage can still be connected to J1 but jumpers J29 and J26 must be removed. In the case of the TPA3223EVM, only 12V can be accepted as a non-5-V Supply and should be connected to pin 2 of J26 (12V). -
Page 13: Reset Circuit And Por
3.8 Reset Circuit and POR The TPA3223EVM includes RESET supervision so that the TPA3223 device remains in reset until all power rails are up and stable. The RESET supervisor also maintains that the device is put into reset if one of the power rails experiences a brown out. -
