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.
