GENERAL DESCRIPTION

The ALD4301A/ALD4301 is a monolithic

high performance quad

voltage comparator built with advanced silicon gate CMOS technol-

ogy. It features very high typical input impedance of 1012

Ω; low input

bias current of 10pA; fast response time of 300ns; very low power

dissipation of 55

µA 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.

The outputs can be connected to a higher external voltage than V+ and

used in a wired-OR connection with other open drain circuits such as

ALD2301/ALD2303. They can also be used with push-pull output

types such as ALD2302/ALD4302 voltage comparators simultaneously

with open drain comparators using a common V+. The ALD4301A/

ALD4301 is ideal for a great variety of voltage comparator applica-

tions, especially detection circuits requiring very low input currents

and low standby power, yet retaining high output current capability.
