[sdiy] low input bias current opamps

[Tim Ressel]

Yo,

Searching all the manufacturers websites can be a pain. What I do is use 
the distributors website as a search engine for parts.

A cursory search on Digikey yielded 2 parts:
OPA404
TLE2064

Actually it yielded more, but when I looked at the datasheets I saw the 
Ib for most of them was <10pA typical but much higher max. The two above 
are <10pA max. Make sure you look at the datasheet to make sure you 
aren't being punked.
