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 1012Ω; 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.
FEATURES
• Guaranteed to drive 200Ω loads
• Fanout of 30LS TTL loads
• Low supply current of 175µA each comparator
• Pinout of LM193 type industry standard comparators
• Extremely low input bias currents -- 10pA
• Virtually eliminates source impedance effects
• Low operating supply voltage of 4V to 12V
• Single (+5V) and dual supply (±5V) operation
• High speed for both large and small signals -- 180ns for TTL inputs and 400ns for 20mV overdrive
• CMOS, NMOS and TTL compatible
• Push-pull outputs-current sourcing/ sinking
• High output sinking current -- 60mA
• Low supply current spikes
