I'm designing a precise measurement circuit and I'm in need of an op amp that has a very low input bias current and that can work in at least -5,+5 voltage range (-10,+10 desired). I need it for voltage followers and curent-to-voltage conversions. The slew rate isn't a priority, but around 2V/us should be ok.
The pieces I've seen in the precision Low Input Bias Current Amplifiers (<100 pA) selection tool are mostly single power source amps. Can anoyone advice me in choosing the right one for my needs?
Some of the other choices are:
ADA4610-2 if you need a dual
AD8510, and ADA4610-2
All of these are stable at gain of 1 for your voltage follower
