TS391 Low power, single voltage comparator - 1

Low-power single voltage comparator Datasheet — production data ■ Wide single supply voltage range or dual ■ Very low supply current (0.2 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. ■ Low input offset voltage: +1 mV typ. ■ Input common-mode voltage range includes ■ Low output saturation voltage: 250 mV typ. ■ Differential input voltage range equal to the supply voltage ■ TTL, DTL, ECL, CMOS compatible outputs This device consists of a low-power voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also This comparator also has a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
