GENERAL DESCRIPTION
The ALD2303A/ALD2303 is a precision monolithic high performance dual voltage comparator built with advanced silicon gate CMOS technology. It features very high typical input impedance of 1012W; low input bias current of 10pA; very low power dissipation of 7.5mA 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.
