Features
Description
This device consists of four independent precision
voltage comparators. All these comparators are
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 the negative rail even
though operated from a single power supply
voltage.
April 2009
Wide single supply voltage range or dual
supplies for all devices: +2 V to +36 V or ±1 V
to ±18 V
Very low supply current (1.1 mA) independent
of supply voltage (1.4 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
