Low Power Dual Voltage Comparators
■ Wide single-supply voltage range or dual
supplies: +2V to +36V or ±1V to ±18V
■ Very low supply current (0.4mA) independent
of supply voltage (1mW/comparator at +5V)
■ Low input bias current: 25nA typ.
■ Low input offset current: ±5nA typ.
■ Low input offset voltage: ±1mV typ.
■ Input common-mode voltage range includes
ground
■ Low output saturation voltage: 250mV typ. (Io =
4mA)
■ 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.
