Opamp replacement

  1. Aug 5, 2009 #1
    Can PNP input opamps be replaced with NPN input ones?
    I want to replace the LM324N with something better.

    A FET rail-to-rail opamp would be able to replace the 324. The PNP topology was just used for some applications before good FET opamps were viable.
