TAS5721: Register settings for PBTL Mode

Part Number: TAS5721
Other Parts Discussed in Thread: CONTROLCONSOLE

I am trying to use the TAS5721 in PBTL mode with two 8 ohm speakers in parallel.

Attached is the file I am using to set the EVM in PBTL. Could this file be verified if it is correct or missing something?

Thanks,

Hi Dennis

The PBTL related registers seems fine. The other registers work for different functions, may not have a clear standard to decide right or wrong, if they fit for your using, would be no problem.

When I use this file and connect 4ohm speaker to Out A and Out D The amp is pulling 1.5A and the sound level is very low?Would you be able to provide me with a configuration for PBTL using OUT A and OUT D?

Hi Dennis.

Could you install the TAS57xx ControlConsole Gui and follow the steps showed in the user guide to have another try?

That actually helped, I din't know I had to remove C25 for PBTL mode.

Thanks,

Dennis
