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.
(Io = 4 mA)
■ Differential input voltage range equal to the
supply voltage
■ TTL, DTL, ECL, MOS, CMOS compatible
outputs
■ ESD internal protection: 2 kV
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.
All the pins are protected against electrostatic
discharge up to 2 kV. As a consequence, the input
voltages must not exceed the magnitude of VCC+
or VCC-.
