1 Low power single channel OPAmp NJMA/NJMA Features Input offset voltage :.mv max. Input offset voltage drift : µv/ typ. Supply current :.ma typ. at Vcc + =V Input bias current : na typ. Input commonmode voltage range includes ground Internal ESD protection : Human body model (HBM)±V typ. Integrated EMI filter : EMIRR=8dB f=.8ghz Wide single supply voltage range or dual supplies +V to +V or ±.V to ±6V Description The NJMA / NJMA 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 OPAmp circuits, which now can be more easily implemented in single power supply systems. For example, the NJMA / NJMA can be directly operated off of the standard +V power supply voltage, which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±V power supplies.

Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of VCC + The normal amplifier operation input voltage is within Common Mode Input Voltage Range specified in the Electrical characteristics.. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collectorvase junction of the input PNP transistor becoming forwardbiased and thereby acting as input diode clamp. In addition to this diode action, there is NPN parasitic action on the IC chip. This transistor action can cause the output voltages of the Opamps to go to the VCC voltage level (or to ground for a large overdrive) for the time during which an input is driven negative.. Shortcircuit can cause excessive heating and destructive dissipation. Values are typical.. Mounted on glass epoxy board. (76...6mm:based on EIA/JDEC standard, Layers FR).Mounted on glass epoxy board.

9 EMIRR [db] NJMA/NJMA APPLICATION NOTE EMIRR(EMI Rejection Ratio) Definition EMIRR is a parameter indicating the EMI robustness of an OPAmp. The definition of EMIRR is given by the following a formula (). We can grasp the tolerance of the RF signal by measuring an RF signal and offset voltage shift quantity. Offset voltage shift is small so that a value of EMIRR is big. And it understands that the tolerance for the RF signal is high. In addition, about the input offset voltage shift with the RF signal, there is the thinking that influence applied to the input terminal is dominant. Therefore, generally the EMIRR becomes value that applied an RF signal to +INPUT terminal.
