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 1012Ω; low input bias current of 10pA; fast response time of 120ns; very low power dissipation of 150µA 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.
