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

Ω; low input bias current of 10pA; very low power

dissipation of 7.5

µA 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.
