Re: uBitX - problem with power draw and failed chip

 

Hey Mike,

I know why it didn't work, it doesn't glow in the dark:-) No seriously folks, that's a bummer. The TDA2822M's speaker output is not referenced to ground and must be isolated from ground. It's a BTL amp. I toasted one first time I used it because I didn't know this. Just a thought.
