LM2903
Low power dual voltage comparator
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. Input common-mode voltage range includes negative rail 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 P TSSOP8 (Thin shrink small outline package) D SO-8 (Plastic micropackage) N DIP8 (Plastic package)

Description
This device consists of two independent low power 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: the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.
