Input commonmode voltage range includes negative rails Differential input voltage range equal to the power supply voltage Large output voltage swing : V to (V CC +.5V) Internal ESD protection Human body model (HBM) ±V typ. Wide power supply range: Single supply: +V to +V Dual supplies: ±.5V to ±5V Description The NJM58C consist of two independent, highgain, internally frequencycompensated opamps, specifically designed to operate from a single power supply over a wide range of voltages. The lowpower supply 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 can now be more easily implemented in single power supply systems. For example, these circuits can be directly supplied with the standard +5V, which is used in logic systems and will easily provide the required interface electronics with no additional power supply. In linear mode, the input commonmode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage.

Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of V CC 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 V CC 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. 4. EIA/JEDEC STANDARD Test board (76. x 4. x.6mm, layers, FR4) mounting 5.

APPLICATION Improvement of Crossover Distortion Equivalent circuit at the output stage NJM94C,in its static state ( No in and output condition ) when design,q U being biassed by constant current ( break down beam ) yet,q L stays OFF. While using with both power source mode,the crossover distortion might occur instantly when Q L ON. There might be cases when application for amplifier of audio signals,not only distortion but also the apparent frequency bandwidth being narrowed remarkably. It is adjustable especially when using both power source mode,constantly to use with higher current on Q U than the load current ( including feedback current ),and then connect the pulldown resister R P at the part between output and V pins. ver.9 9
