GENERAL DESCRIPTION

The ALD2302A/ALD2302 are monolithic precision high performance dual voltage comparators built with advanced silicon gate CMOS technology. The primary features are: very high typical input impedance of 1012?; low input bias current of 10pA; fast response time of 180ns; very low power dissipation of 175μA per comparator; and single (+5V) or dual (±5V) power supply operation.
