Low Power Single Voltage Comparator

Data Sheet


  • Wide single supply voltage range or dual supplies (
    +2V to +36V or ±1V to ±18V)
  • Very low supply current (0.3mA typ. at Vcc+=5V)
  • Low input bias current (20nA typ.)
  • Low input offset current (0.5nA typ.)
  • Low input offset voltage (0.5mV typ. 3mV max.)
  • Input common-mode voltage range includes ground
  • Low output saturation voltage (80mV typ. (Isink = 4mA))
  • Differential input voltage range equal to the supply voltage
  • TTL, DTL, ECL, MOS, CMOS compatible outputs
  • Internal ESD protection
  • Human body model (HBM) (±2000V typ.)

General Description

The NJM390A/NJM391A are single comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. The NJM390A/391A also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.
