Rail-rail opamp, low low noise, 25v or so?

I do think the AD820 will be the one we use but I have samples of a number of opamps coming tomorrow for testing.

The LT1007 is not rated for a single supply, that means that if I were to use ground as VDD, the opamp would not swing close enough to ground to be of any use.

The older tuner used to have GaAs switches that needed negative biasing. We moved to CMOS and we no longer need any negative biasing. if we can keep from using a negative rail on the opamps, we can get rid of the regulation and all associated parts/traces. That would be a good space and cost savings. Because of this I am trying everything to use a single supply opamp.

I'm pretty sure that I have good choices to choose from.

Thanks again!
