 		 #76040 - RE: Chopper Op_Amps
Responding to: ???'s previous message
I was referring to the op-Amp offset. The first thing to be tackled with at this stage [ Op-Amp selection stage ] is ofcourse op-Amp offset. The circuitary offset can't be predicted at this stage, .......
My welding machines use AC current

Why no AC couple the amplifier = NO offset?
