TAS5825M: about TAS5825M OUTPUT circuit

Tom Shih

Part Number: TAS5825M

Hi TI

We RF team suggests adding RF De-sense R/C to the TAS5825M circuit each OUTPUT path, this is ok?

(R520,R521,R522,R523,C520,C521,C522,C523)

What should we pay attention to?

Thanks!

Hi Tom,

Just to confirm, you're wanting to implement an RC snubber circuit on the outputs to improve EMI performance?

If so, this is common but I would place the resistor in parallel with the outputs.

This app note should be helpful: Class-D Output Snubber Design.

Regards,

Sebastian
