NJM2904D

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. ■ FEATURES ● Single Supply ● Operating Voltage ● Low Operating Current ● Slew Rate ● Bipolar Technology ● Package Outline ■ PACKAGE OUTLINE NJM2904D NJM2904M NJM2904E NJM2904V NJM2904RB1 NJM2904L ( +3V~+32V ) ( 0.7mA typ. ) ( 0.5V/µs typ. ) DIP8, DMP8, EMP8, SSOP8, TVSP8, SIP8 ■ PIN CONFIGURATION ( Top View ) 8 1 2 3 4 A 7 B A B 6 5 1 NJM2904D, NJM2904M NJM2904E, NJM2904V NJM2904RB1 2 3 4 5 NJM2904L 6 7 8 PIN FUNCTION 1.

While using with both power source mode,the cross-over distortion might occur instantly when QL 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 QU than the load current ( including feedback current ),and then connect the pull-down resister RP at the part between output and GND pins.
