GENERAL DESCRIPTION

The ALD2303A/ALD2303 is a precision monolithic high performance dual voltage comparator built with advanced silicon gate CMOS technology. It features very high typical input impedance of 1012Ω; low input bias current of 10pA; very low power dissipation of 7.5µA per comparator; and single (+5V) or dual (±5V) power supply operation.

FEATURES
