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
