ADVANCED LINEAR DEVICES, INC. ALD4302A/ALD4302 QUAD PRECISION CMOS VOLTAGE COMPARATOR WITH PUSH-PULL DRIVER GENERAL DESCRIPTION The ALD4302 is a monolithic high performance quad 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 120ns; very low power dissipation of 150 A per comparator; and single +5V or dual ±5V power supply operation. The input voltage range includes ground, making this comparator ideal for single supply low level signal detection with high source impedance. The outputs can source and sink current, allowing application flexibility, and can be used in either wired-OR connection without pull up resistor or push-pull configuration. The ALD4302 can be used in wired-OR connection with other open drain circuits such as the ALD2301 and ALD2303 voltage comparators. The ALD4302 is ideal for a great variety of precision voltage comparator applications, especially low level signal detection circuits requiring low standby power, yet retaining high output current capability. FEATURES Guaranteed to drive 200 loads Fanout of 30 LS TTL loads Low supply current of 150A each comparator Extremely low input bias currents -- 10pA 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 and small signals 120ns for TTL inputs and 400ns for 5m……
