GENERAL DESCRIPTION
The ALD2301A/ALD2301B/ALD2301/ALD2301C is a monolithic high
performance dual voltage comparator built with advanced silicon gate
CMOS technology. It features very high typical input impedance of
10
low power dissipation of 55 A per comparator; and single +5V or dual
The input voltage range includes ground, making this comparator ideal
for low level signal detection with high source impedance. The outputs
are open-drain configuration, allowing maximum application flexibility,
such as wired-OR connection. The outputs can be connected to a
higher external voltage than V
The ALD2301A/ALD2301B/ALD2301/ALD2301C is ideal for a great
variety of voltage comparator applications, especially low level signal
detection circuits requiring low standby power, yet retaining high
output current capability as needed.
