SINGLE-SUPPLY DUAL OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM2904 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 NJM2904 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.
