TS391IL Datasheet PDF - ST Microelectronics

●Description

●These devices consist 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 possible.

●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.

●■ Wide single supply voltage range or dual supplies +2V to +34V or ±1V to ±17V

●■ Very low supply current (0.2mA) independent of supply voltage (1mW/comparator at +5V)

●■ Low input bias current: 25nA typ.

●■ Low input offset current: ±5nA typ.

●■ Low input offset voltage: ±1mV typ.

●■ Input common-mode voltage range includes ground

●■ Low output saturation voltage: 250mV typ. (Io=4mA)

●■ Differential input voltage range equal to the supply voltage

●■ TTL, DTL, ECL, CMOS compatible outputs
