Hi,

Is there a possibility that TPA3220 will be damaged by the following use case?

- Resonance due to no load
- Connecting capacitive loads like piezo

Hi Kato

There's shouldn't be damage for the using conditions.

Open load is no problem, and device will normally output waveform.

Piezo load will easily create OC, suggested use a 10ohm power resistor to in series with the piezo.
