Hello,I'm using an LM324 in a simple circuit to drive a 20mA relay. With no load, it takes 1mA from the 12v supply.As I'll eventually be using batteries, 8 x AA, I'd dearly like this to be a lot less, perhaps under 100uA?
I've browsed around, but the 324 (whose output will go to 0v, which I need) has the lowest supply current I've found.
Anyone more knowledgeable than google
?
Thanks,
