ALD2302A/ALD2302
DUAL PRECISION CMOS VOLTAGE COMPARATOR WITH PUSH-PULL DRIVER
GENERAL DESCRIPTION
The ALD2302A/ALD2302 are monolithic precision high performance dual voltage comparators built with advanced silicon gate CMOS technology. The primary features are: very high typical input impedance of 1012Ω; low input bias current of 10pA; fast response time of 180ns; very low power dissipation of 175µA per comparator; and single (+5V) or dual (±5V) power supply operation.
The input voltage range includes ground, which makes these comparators ideal for single supply low level signal detection with high source impedance. The outputs can source and sink current allowing for application flexibility. They can be used in either wired-OR connection without pull-up resistor or push-pull configuration. The ALD2302A/ ALD2302 can also be used in wired-OR connection with other open drain circuits such as the ALD2301/ALD2303 voltage comparators.
The ALD2302A/ALD2302 voltage comparators are ideal for a great variety of applications, especially in low level signal detection circuits which require low standby power and high output current. For quad packages, use the ALD4302A/ALD4302 quad voltage comparator.
