I had design with TPA6211A1.
test condition that audio signal supply to tpa6211A1 during shutdown pin is "high", when we main power off -> on , it happen to pop up noise.
I'd like to prevent this pop up noise during this condition. Please help to me.
thanks
Hi, Lee Byung,
That's a pretty tough situation to protect against. Can you put the part in shutdown before the power goes away? Like some kind of SVS circuit...
