Low power dual voltage comparators
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.
Low input offset voltage: ±1 mV typ.
Input common-mode voltage range includes
ground
Low output saturation voltage: 250 mV typ.
(I
sink
= 4 mA)
Differential input voltage range equal to the
supply voltage
TTL, DTL, ECL, MOS, CMOS compatible
outputs

Description
These devices consist of two independent low
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 in that the input common-mode
voltage range includes ground even though
operated from a single power supply voltage.
