Features
•
Wide single supply voltage range or dual
supplies: 2 V to 36 V or ±1 V to ±18 V
Very low supply current (0.4 mA)
independent of supply voltage
(1 mW/comparator at 5 V)
Low input bias current: 25 nA typ.
Low input offset current: ±5 nA typ.
Input common-mode voltage range includes
ground
Description
This device consists of two independent low-
power voltage comparators designed specifically
to operate from a single power supply over a
wide range of voltages. Operation from split
power supplies is also possible.
•
•
•
•
These comparators also have
a
unique
characteristic in that the input common-mode
voltage range includes ground even though
operated from a single power supply voltage.
•
Low output saturation voltage: 250 mV typ.
(IO = 4 mA)
