LM3886: need support to select mute capacitance of LM3886

Sowmiya annamalai

Part Number: LM3886

Hi,

I have attached the application circuit of LM3886T/NOPB from datasheet. Can you confirm that ECA-1CM101I (100uF) from Panasonic can be used as mute capacitance?

Hi,

The Mute capacitance set up to create a large time constant for turn-on and turn-off muting.

ECA-1CM101I part number looks fine.

Hi,

Thanks for the support.

Rm - 15000, Cm - 100uF

Time constant -1.5s (typ)

Is this time constant okay?
