ADVANCED LINEAR DEVICES, INC. ALD4301A/ALD4301 QUAD PRECISION CMOS VOLTAGE COMPARATOR WITH OPEN DRAIN DRIVER GENERAL DESCRIPTION The ALD4301A/ALD4301 is a monolithic high performance quad voltage comparator built with advanced silicon gate CMOS technology. It features very high typical input impedance of 10 12 ; low input bias current of 10pA; fast response time of 300ns; very low power dissipation of 55 A per comparator; high output drive 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. The outputs can be connected to a higher external voltage than V + and used in a wired-OR connection with other open drain circuits such as ALD2301/ALD2303. They can also be used with push-pull output types such as ALD2302/ALD4302 voltage comparators simultaneously with open drain comparators using a common V+. The ALD4301A/ ALD4301 is ideal for a great variety of voltage comparator applications, especially detection circuits requiring very low input currents and low standby power, yet retaining high output current capability. FEATURES Fanout of 30 LS TTL loads Low supply current of 55A/comparator typical Pinout/Functional equivalent to LM393 types Extremely low input bias currents -- 10pA typical Virtually eliminates source impedance effects Low operating supply v……
