ALD2301A

ADVANCED LINEAR DEVICES, INC. ALD2301A/ALD2301B ALD2301C/ALD2301 DUAL PRECISION CMOS VOLTAGE COMPARATOR WITH OPEN DRAIN DRIVER GENERAL DESCRIPTION The ALD2301A/ALD2301B/ALD2301C/ALD2301 is a 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; 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+. The ALD2301A/ALD2301B/ALD2301C/ALD2301 is ideal for a great variety of voltage comparator applications, especially low level signal detection circuits requiring low standby power, yet retaining high output current capability as needed. FEATURES Fanout of 30LS TTL loads Low supply current of 110µA typical Functional equivalent to LM193 industry standard comparators Extremely low input bias currents -- typically 10pA Virtually eliminates source impedance effects Low operating supply voltage of 3V to 10V 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...
