    ... It is generally recognized that any circuit which must operate with less than 1000 pA of leakage current requires special layout of the PC board. When one wishes to take advantage of the ultra-low input current of the LMC6462/4, typically 150 fA essential to have an excellent layout. Fortunately, the techniques of obtaining low leakages are quite simple. First, ...
