TAS6424-Q1: TAS6424-Q1 with capacitive load only

Part Number: TAS6424-Q1
Other Parts Discussed in Thread: TAS6424

Hello Team,

is there any restriction for the TAS6424 when amplifier has to drive an AC load only?
In this configuration there is only a loudspeaker with capacitors in series and no DC load in parallel connected.
Anything to care about? And same question also for TPA6404.

Many Thanks

Josef

Hi Josef,

Can you share the speaker spec to us? We need to evaluate the application.

Thanks!

Regards,

Derek

Josef,

This has been thoroughly tested and we do not see any audio issues. We only see DC load diagnostic issues since the speaker is obviously not DC connected, and should use AC Diagnostics for speaker detection.
