This is a Low Offset Voltage Dual Comparator.

The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range− to−ground level with single supply operation. Input offset voltage specifications as low as
2.0 mV make this device an excellent selection for many applications in consumer, automotive, and industrial electronics.



  • Wide Single−Supply Range: 2.0 Vdc to 36 Vdc
  • Split−Supply Range: ±1.0 Vdc to ±18 Vdc
  • Very Low Current Drain Independent of Supply Voltage: 0.4 mA
  • Low Input Bias Current: 25 nA
  • Low Input Offset Current: 5.0 nA
  • Low Input Offset Voltage: 5.0 mV (max) LM293/393
  • Input Common Mode Range to Ground Level
  • Differential Input Voltage Range Equal to Power Supply Voltage
  • Output Voltage Compatible with DTL, ECL, TTL, MOS, and CMOS Logic Levels
  • ESD Clamps on the Inputs Increase the Ruggedness of the Device without Affecting Performance
