Jan 6, 2022 at 14:59 comment added Christopher Moore @Kartman If my input to the amplifier never goes below 0V would that be an issue? Wouldn't the 12V/2 virtual earth turn my 0-0.6V input into 12V/2-gain*0.6V?

Jan 6, 2022 at 8:55 comment added Kartman I don’t think the digipot would appreciate a negative voltage - check the datasheet. I’d go with the 12V/2 for the virtual earth.
Jan 6, 2022 at 5:58 comment added Christopher Moore @Kartman Would just using a split supply with the -12V instead of ground to the opamp work?
Jan 6, 2022 at 5:10 comment added Christopher Moore @Kartman I was not aware that was a thing. After some reading I believe that means I need to replace the ground on my pot with 12V/2?
Jan 6, 2022 at 5:02 comment added Kartman You're running single supply, where's the virtual earth?
