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.
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.
