Anyone have a favorite opamp that can do rail to rail around 25v? I'm looking for something with as low noise(V and I) as possible..
I'm playing around with wideband VCOs and I need as many different opamps to try as level shifters. The PLL I am using only goes from 0-5vdc but the only options I have for VCOs seem to be 0-20v(with the bandwidth that I want to use).
I am using an LT1038 right now but it only gets within 2v of the rails(ground and VCC) and I don't want to end up biasing it with a negative rail if I don't have to.
Another idea is to use some kind of discrete transistor but I really don't want to spend an excessive amount of time getting that right... Any opinions?
