描述 Description

GENERAL DESCRIPTION
The ALD2301A/ALD2301B/ALD2301/ALD2301C is a monolithic high performance dual voltage comparator built with advanced silicon gate CMOS technology. It features very high typical input impedance of 1012?; low input bias current of 10pA; fast response time of 300ns; very low power dissipation of 55μA per comparator; and single +5V or dual ±5V power supply operation.
The input voltage range includes ground, making this comparator ideal for low level signal detection with high source impedance. The outputs are open-drain configuration, allowing maximum application flexibility, such as wired-OR connection. The outputs can be connected to a higher external voltage than V+.FEATURES
? Fanout of 30 LS TTL loads
? Low supply current of 110μA typical
? Functional equivalent to LM193 industry standard comparators
? Extremely low input bias currents -- 10pA typical
? Virtually eliminates source impedance effects
? Low operating supply voltage of 3V to 12V
? Single +5V and dual supply ±5V operation
? High speed for both large signal and low level signals -- 300ns typical for TTL inputs
? CMOS, NMOS and TTL compatible
? Wired-OR open drain outputs
? High output sinking current -- 60mA typical
? Low supply current spikesAPPLICATIONS
