This device consists of four independent precision voltage comparators, which 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.
**Key Features**
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
