Other Parts Discussed in Thread: TPA2011D1

Hi,

Is TPA2011D1 damaged by the back electromotive force if it is repeated the power on/off with the LC filter during the audio playback?
Could you please give us your advice about it?

Best regards,
Kato

Hi, Kato-san,

Using a typical LC filter design, this is not an issue.

Hi Don-san,

Thank you for your reply.
Do you recommend to use the LC filter(a ferrite bead and a 1nF capacitor) is mounted on the evm?
Could you please tell me the value of the LC filter which you recommend since I could not find it in the data sheet if it isn't correct?

Best regards,
Kato
