LM2901
Low power quad voltage comparator
Features

Wide single supply voltage range or dual supplies for all devices: +2V to +36V or 1V to 18V Very low supply current (1.1mA) independent of supply voltage (1.4mW/comparator at +5V) Low input bias current: 25nA typ. Low input offset current: 5nA typ. Input common-mode voltage range includes negative rail 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
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.
