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
• 3V, 5V and 12V supply
• Guaranteed to drive 200Ω loads
• Fanout of 30LS TTL loads
• Guaranteed maximum supply current of 20µA for each comparator
• Pinout of LM193 type industry standard comparators
• Extremely low input bias currents -- 10pA
