ABSTRACT:
Disclosed in a differential operational amplifier for use with a proximity type pick up. It has a common mode rejection input circuit comprising a diode and transistor connected to each input as well as diodes connected across the amplifier differential inputs. Common mode signals are clamped at the input to both protect the amplifier and prevent false transitions at the output.
