NJM2902M
NJM2902 QUAD SINGLE-SUPPLY OPERATIONAL AMPLIFIER ■ GENERAL DESCRIPTION The NJM2902 consists of four independent high-gain operational amplifiers that are designed for single-supply operation. Operation from split power supplies is also possible and the low power supply drain is independent of the magnitude of the power supply voltage. Used with a dual supply the circuit will operate over a wide range of supply voltages. However, a large amount of crossover distortion may occur with loads to ground. An external current-sinking resistor to-VS will reduce crossover distortion. There is no crossover distortion problem in single-supply operation if the load is direct-coupled to ground. ■ FEATURES ● Single Supply ● Operating Voltage ● High Output Voltage ● Slew Rate ● Low Operating Current ● Package Outline ● Bipolar Technology ■ PACKAGE OUTLINE NJM2902N NJM2902M NJM2902V ( +3V~+32V ) ( V+-2V ) ( 0.5V/μs typ. ) ( 1mA typ. ) DIP14, DMP14, SSOP14 ■ PIN CONFIGURATION NJM2902N, NJM2902M NJM2902V 1 2 14 A D 13 3 12 4 11 5 6 7 10 B C 9 8 PIN FUNCTION 1.A OUTPUT 2.A –INPUT 3.A +INPUT + 4.V 5.B +INPUT 6.B –INPUT 7.B OUTPUT 8.C OUTPUT 9.C -INPUT 10.C +INPUT 11.V 12.D +INPUT 13.D -INPUT 14.D OUTPUT ■ EQUIVALENT CIRCUIT ( 1/4 Shown ) V- Ver.2014-04-21 -1-
