Hello, I'll keep this one short. :) I like the CA3140 but can't find a working spice model for single rail voltage follower operation so it won't let me model some of the weird things I found that chip useful for. It's still made, and I'll ask Intersil if they can give me a model, but it might be time to look for something widely used, multi-sourced, capable of the same things a CA3140 can do. I don't mind if has no strobe though.
Any specific IC's I should look at? (Googling CA3140 substitutes is like asking monkeys instead of experts, so I have to ask here too, because Google is like a lucky dip with lousy prizes, at times. I find comparisons with obsolete IC's, or with the 741 (!) or with abysmal slew rates...) So I need to ask people who have a clue about this. :)
