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.
