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 10
12
; low input bias current of 10pA; very low power
dissipation of 7.5
μ
A 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/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 ALD2301/ALD2303. They can also be used with
push-pull output types such as ALD2302/ALD4302 voltage compara-
tors simultaneously with open drain comparators using a common V+.
The ALD4303A/ALD4303 is ideal for a great variety of voltage com-
parator applications, especially micropower detection circuits requiring
very low input currents, high output currents and low standby power.
