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 1012Ω; low input bias current of 10pA; fast response time of 300ns; very low power dissipation of 55µA 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.
