Low power single channel Op-Amp

Data Sheet


  • Input offset voltage (2.5mV max.)
  • Input offset voltage drift (5µV/°C typ.)
  • Supply current (0.45mA typ. at Vcc+=5V)
  • Input bias current (20nA typ.)
  • Input common-mode voltage range includes ground
  • Integrated EMI filter (EMIRR=84dB typ. @ f=1.8GHz)
  • Wide single supply voltage range or dual supplies (
    +3V to +32V or ±1.5V to ±16V)

General Description

The NJM320A / NJM321A consist of two independent, high gain, internally frequency compensated operation amplifiers, which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks, and all the conventional op amp circuits, which now can be more easily implemented in single power supply systems. For example, the NJM320A / NJM321A can be directly operated off of the standard +5V power supply voltage, which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15V power supplies.
