Op Amps as Comparators
... An ideal op amp has infinite Zin and zero bias current Real life is not so pretty Except with current-feedback op amps (which have asymmetric input structures and should not be used as comparators) it is reasonable to assume that C and Ib are small and R is large But designs must consider the effect ...
