Hi Noki,

For PBTL configuration, you can refer Figure 24 in datasheet.

Hi Ian,

This is not a common case, I'm not sure if there will be any unexpected issue. To achieve this, you will need to, connect the two TAS5634 devices' output in post filter PBTL mode.

Sam

Hi Derek,

I need to connect 2 tas5634s in parallel to drive 1200W speakers,

Is the connection shown in the figure below correct?

Can you provide a suggested circuit diagram?

Thank you

Hi,

There is only one PWM input pair. I corrected the diagram as below,

For other settings, just follow the PBTL configurations in Figure 29 on datasheet.

Please note that this is not a typical case within TI spec/application. Although we don't see any problem till now, we can't guarantee it would work without any problem.

Thanks!

Regards,

Sam
