| NJM2120 OPERATIONAL AMPLIFIER WITH SWITCH GENERAL DESCRIPTION The NJM2120 is a dual operational amplifier of 2-INPUT and 1-OUTPUT with analog switch.The NJM2120 can be used as analog switch under the condition of GV=0dB,as Switch + Amp in order that each gain (A or B) can be adjusted independently.Each amplifier of the NJM2120 has the same electrical characteristics as the NJM4558. The NJM2120 is suitable for Audio,Video,Electrical musical instrument...etc. FEATURES Analog Switch Function Operating Voltage Slew Rate Wide Unity Gain Bandwidth Package Outline Bipolar Technology PIN CONFIGURATION PIN FUNCTION 1.SW.CONTROL 2.A +INPUT 3.A -INPUT 4.V 5.OUTPUT 6.B -INPUT 7.B +INPUT + 8.V PACKAGE OUTLINE NJM2120D NJM2120M ( 2.5V~18V ) ( 2.2V/s typ. ) ( 7MHz typ. ) DIP8,DMP8,SIP8 NJM2120L NJM2120D NJM2120M NJM2120L EQUIVALENT CIRCUIT Ver.2003-03-18 -1- NJM2120 ABSOLUTE MAXIMUM RATINGS ( Ta=25C ) PARAMETER Supply Voltage Differential Input Voltage Input Voltage Output Current Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL +V /V VID VIC IO PD Topr Tstg RATINGS 18 30 15 50 ( DIP8 ) 500 ( DMP8 ) 300 ( SIP8 ) 800 -40~+85 -40~+125 UNIT V V V mA mW C C ELECTRICAL CHARACTERISTICS ( V+/V-=15V,Ta=25C ) PARAMETER Operating Current Input Offset Voltage Input Bias Current Large Signal Voltage Gain Maximum Output Voltage Swing Total Harmonic Distortion Supply Voltage Rejection Ratio Channel Separation Unity Gain Bandwidth Slew Rate Equivalent Input Noise Voltage SYMBOL ICC VIO IB AV VOM THD SVR CS fT SR VNI VIN TEST CONDITION SW ON SW OFF RS=10k MIN. 12 TYP. 2.3 2.1 0.8 80 100 14 0.002 20 82 7 2.2 2.0 MAX. 6.0 6.0 6.0 500 150 UNIT mA mA mV nA dB V % V/V dB MHz V/s Vrms RL=2k RL=10k f=1kHz,VO=5Vrms,GV=20dB f=1kHz GV=0dB GV=0dB,RL=2k//100pF RS=1k,BW=10Hz~30kHz,Flat -2- Ver.2003-03-18 NJM2120 TEST CIRCUIT Ver.2003-03-18 -3- NJM2120 TYPICAL CHARACTERISTICS -4- Ver.2003-03-18 NJM2120 APPLICATION CIRCUIT Ver.2003-03-18 -5- NJM2120 TYPICAL APPLICATION CIRCUIT -6- Ver.2003-03-18 NJM2120 SHOCK NOISE TEST Ver.2003-03-18 -7- NJM2120 CHANNEL SEPARATION -8- Ver.2003-03-18 NJM2120 SWITCHING MECHANISM [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
