Features & Applications

The LM193DT is a 100 nA average bias current and dual voltage comparator with 2 V to 36 V supply voltage. Its available in surface mount SOIC-8 package.

This device consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages.


  • 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 DIP8, SO-8, TSSOP8, MiniSO-8, and DFN8 2 x 2 mm packages
