Low Power Dual Voltage Comparator

Data Sheet


  • Wide single supply voltage range or dual supplies (
    +2V to +36V or ±1V to ±18V)
  • Very low supply current (0.45mA typ. at Vcc+=5V)
  • Low input bias current (20nA typ.)
  • Input common-mode voltage range includes ground
  • Low output saturation voltage (80mV typ. (Isink = 4mA))
  • Differential input voltage range equal to the supply voltage (±36V)
  • TTL, DTL, ECL, MOS, CMOS compatible outputs
  • Internal ESD protection (Human body model (HBM) ±2000V typ.)
  • Input Offset Voltage Grade (
    NJM393C(normal-Grade): 5mV max. at Ta=25°C, 9mV max.at Ta=0 to 70°C
    NJM393CA(A-Grade): 2mV max. at Ta=25°C, 4mV max.at Ta=0 to 70°C)

General Description

The NJM393C/NJM393CA consist of two independent low power 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.
