GENERAL DESCRIPTION
The ALD2303A/ALD2303 is a precision monolithic high performance
dual voltage comparator built with advanced silicon gate CMOS tech-
nology. It features very high typical input impedance of 10
12
Ω; low
input bias current of 10pA; very low power dissipation of 7.5µA per
comparator; 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 ALD2303A/ALD2303 can be used in connection with other voltage
comparator circuits such as the ALD2301/ALD2302/ALD4302 voltage
comparators. The output can be connected to a higher external voltage
than V
+
.
The ALD2303A/ALD2303 is ideal for high precision micropower voltage
comparator applications, especially low level signal detection circuits
requiring low standby power, yet retaining high output current
capability.
