NJM2904 SINGLE-SUPPLY DUAL OPERATIONAL AMPLIFIER ■ GENERAL DESCRIPTION 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, .

NJM2904 SINGLE-SUPPLY DUAL OPERATIONAL AMPLIFIER ■ GENERAL DESCRIPTION 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. ■ PACKAGE OUTLINE NJM2904D NJM2904E NJM2904R/RB1 ■ FEATURES ● Single Supply ● Operating Voltage ● Low Operating Current ● Slew Rate ● Bipolar Technology ● Package Outline ■ PIN CONFIGURATION +3V~+32V 0.7mA typ. 0.5V/μs typ.
