TAS5766M: Question of RC Snubber Location of the TAS5766M

Wayne Chen (Audio AE)

Part Number: TAS5766M

Hi Sirs,

With ferrite bead design (no RC filter) with the TAS5766M, should we place the RC snubber before (location #1) or after (location #2) the ferrite beads? Which location is better? How can we adjust the RC snubber values for EMI suppression?

Thank you and Best regards,

Hello Wayne! Much oif this depends on what you are trying to accomplish, or what matters most in the design. Usually close to the output pins is best. Please reference the following, which also have some good reference documents embedded.

Andy, Do you have any other suggestions?

Thanks, Jeff
