LM393 Datasheet PDF - ST Microelectronics

The LM193, LM293, and LM393 devices consist of two independent low 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 in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

●Key Features

● Wide single-supply voltage range or dual supplies: 2 V to 36 V or ±1 V to ±18 V

● Very low supply current (0.45 mA) independent of supply voltage (1 mW/comparator at 5 V)

● Low input bias current: 20 nA typ.

● Low input offset current: ±3 nA typ.

● Low input offset voltage: ±1 mV typ.

● Input common-mode voltage range includes ground

● Low output saturation voltage: 80 mV typ. (Isink  = 4 mA)

● Differential input voltage range equal to the supply voltage

● TTL, DTL, ECL, MOS, CMOS compatible outputs

● Available in DFN8 2x2, MiniSO8, TSSOP8, and SO8 packages
