Here are the standards:
Slew rate is what you should care about when evaluating an op-amp. You want to look at the time it takes to go from 0V (black) to 1V (white). That time should be less than or close to 1x SD pixel (about 70 ns.)
LM6172 is getting more and more expensive since TI bought out National. But there aren’t any real alternatives with the same specs, price, available in DIP, and that can run on +/-12V power rails. We’re moving to SMT for our next rendition of DIY designs, and using the same opamps we use for production (ADA4851-x series, running on +/-5V power rails.)
