ORDERING INFORMATION

GENERAL DESCRIPTION

The ALD2301A/ALD2301B/ALD2301C/ALD2301 is a monolithic high

performance dual voltage comparator built with advanced silicon gate

CMOS technology. It features very high typical input impedance of

very low power dissipation of 55µA per comparator; 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, such as wired-OR connection. The outputs can be con-

nected to a higher external voltage than V

The ALD2301A/ALD2301B/ALD2301C/ALD2301 is ideal for a great

variety of voltage comparator applications, especially low level signal

detection circuits requiring low standby power, yet retaining high

output current capability as needed.
