NJM072B/082B/072/082 DUAL J-FET INPUT OPERATIONAL AMPLIFIER ■ GENERAL DESCRIPTION The NJM072B/082B & NJM072/082 are dual JFET input operational amplifiers. They feature low input bias and offset currents, high input impedance and fast slew rate. The low harmonic distortion and low noise make them ideally suit for amplifiers with high fidelity and audio amplifier applications. The NJM072/082 may cause oscillation in some application like voltage follower. ■ FEATURES ● Operating Voltage ● J-FET Input ● High Input Resistance ● Low Input Resistance ● High Slew Rate ● Wide Unity Gain Bandwidth ● Package Outline ( ±4V~±18V ) ( 1012Ω typ. ) ( 30pA typ. ) ( 13V/µs,20V/µs typ. ) ( 3MHz,5MHz typ. ) DIP8, DMP8, SIP8 EMP8 (NJM072B only) SSOP8 (NJM072B/082B only) ■ PACKAGE OUTLINE NJM072BD/082BD NJM072D/082D NJM072BE NJM072BM/082BM NJM072M/082M NJM072BV/082BV NJM072BL/082BL NJM072L/082L ● Bipolar Technology ■ PIN CONFIGURATION NJM072BD/082BD, NJM072D/082D NJM072BM/082BM, NJM072M/082M NJM072BE NJM072BV/082BV PIN FUNCTION 1.A OUTPUT 2.A -INPUT 3.A +INPUT 4.V5.B +INPUT 6.B -INPUT 7.B OUTPUT 8.V+ NJM072L/082L NJM072BL/082BL ■ EQUIVALENT CIRCUIT Ver.2012-08-09 -1- NJM072B/082B/072/082 ■ ABSOLUTE MAXIMUM RATINGS ( Ta=25˚C ) PARAMETER Supply Voltage Input Voltage Differential Input Voltage SYMBOL V+/VVIC VID Power Dissipation PD Operating Temperature Range Storage Temperature Range Topr Tstg RATINGS ± 18 ± 15(note) ± 30 ( DIP8 ) 500 ( DMP8 ) 300 (EMP8) 300 ( SSOP8 ) 250 ( SIP8 ) 800 -40~+85 -40~+125 UNIT V V V mW ˚C ˚C (note) For supply voltage less than±15V, the absolute maximum input voltage is equal to the supply voltage. ■ ELECTRICAL CHARACTERISTICS ( Ta=+25˚C,V+/V-=±15V ) ( ) Applies to NJM082B,NJM082 PARAMETER Input Offset Voltage Input Offset Current Input Bias Current Input Common Mode Voltage Range Maximum Peak-to-peak Output Voltage Swing Large-Signal Voltage Gain Unity Gain Bandwidth SYMBOL VIO IIO IB VICM VOPP AV fT Input Resistance Common Mode Rejection Ratio Supply Voltage Rejection Ratio Operating Current Slew Rate RIN CMR SVR ICC SR Equivalent Input Noise Voltage VNI TEST CONDITION RS=50Ω RL=10kΩ RL≥2kΩ,VO=±10V 072B/082B 072/082 RS≤10kΩ RS≤10kΩ 072B/082B 072/082 RS=100Ω,B.W.=10~10kHz MIN. ± 10 24 88 70 70 - TYP. 3 (5) 5 30 27 106 3 5 1012 76 76 3 13 20 4 MAX. 10 (15) 50 (200) 200 (400) 5 (5.6) - UNIT mV pA pA V VP-P dB MHz MHz Ω dB dB mA V/µs V/µs µVrms ■ NOTICE WHEN APPLICATION Recommendable product 072/082 are the products in which the AC feature have been made much higher comparing to the products of 072B/082B which are compatible with 072/082 type of other company’s products. Therefore, 072/082 are unstable in oscillation when the voltage follower application, and it is recommendable to use the standard type 072B/082B when newly designed. Beside these products, we have NJM2082 which is higher up in AC feature, yet stability in oscillation, and then the driving capacity to the load at the output stage is made much higher in operation. -2- Ver.2012-08-09 NJM072B/082B/072/082 ■ TYPICAL CHARACTERISTICS Ver.2012-08-09 -3- NJM072B/082B/072/082 -4- Ver.2012-08-09 NJM072B/082B/072/082 ■ MEMO [CAUTION] The specifications on this databook are only given for information, without any guarantee as regards either mistakes or omissions.
