Features
Description
This device consists of two independent low
power voltage comparators designed specifically
to operate from a single supply over a wide range
of voltages. Operation from split power supplies is
also possible.
These comparators also have a unique
characteristic: the input common-mode voltage
range includes the negative rail even though
operated from a single power supply voltage.
February 2008
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
negative rail
Low output saturation voltage:
250 mV typ. (I
Differential input voltage range equal to the
supply voltage
