1 NJM94C / NJM94CA SINGLE-SUPPLY DUAL OPERATIONAL AMPLIFIER GENERAL DESCRIPTION The NJM94C / NJM94CA consists 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 NJM94C 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.

7 NJM94C / NJM94CA APPLICATION Improvement of Cross-over Distortion Equivalent circuit at the output stage NJM94C / NJM94CA,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 cross-over 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 pull-down resister R P at the part between output and V - pins.
