I'm looking for a unity-gain, low-power op-amp to replace an AD8244 as a voltage follower. I only need one amplifier circuit (not the four that the AD8244 has) and care about low cost, low current draw, ability to run on a single-ended 3.3 V supply and follow a 1.65 V input with noise being no more than a few uV.
Also, I'm a physics PhD student who has done a lot of electronics work, but this is my first experience designing a PCB and working with surface-mount components. Are certain surface-mount packages easier to work with for relatively inexperienced engineers?
Thanks for your help!
