GENERAL DESCRIPTION
The ALD4303A/ALD4303 is a precision monolithic high performance
quad voltage comparator with open drain output built with advanced
silicon gate CMOS technology. It features very high typical input
impedance of 1012; low input bias current of 10pA; very low power
dissipation of 7.5A per comparator; micropower operation; high
output drive 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 ALD4303A/ALD4303 can be used in connection with
other voltage comparator circuits such as the ALD2301, ALD2302,
and ALD4302 voltage comparators. 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 the ALD2301 and ALD2303.
They can also be used with push-pull output types such as the
ALD2302 and ALD4302 voltage comparators simultaneously with
open drain comparators using a common V+. The ALD4303A/ALD4303
is ideal for a great variety of voltage comparator applications, espe-
cially micropower detection circuits requiring very low input currents,
high output currents and low standby power.
