NJM2120M-TE2

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 ( ±2.5V~±18V ) ( 2.2V/µs typ. ) ( 7MHz typ. ) DIP8,DMP8,SIP8 ■ PACKAGE OUTLINE NJM2120D NJM2120M NJM2120L ■ PIN CONFIGURATION NJM2120D NJM2120M NJM2120L PIN FUNCTION 1.SW.CONTROL 2.A +INPUT 3.A -INPUT 4.V 5.OUTPUT 6.B –INPUT 7.B +INPUT + 8.V ■ EQUIVALENT CIRCUIT Ver.2003-03-18 -1- NJM2120 ■ ABSOLUTE MAXIMUM RATINGS ( Ta=25˚C ) PARAMETER Supply Voltage Differential Input Voltage Input Voltage Output Current SYMBOL + V /V VID VIC IO Power Dissipation PD Operating Temperature Range Storage Temperature Range 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=25˚C ) 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 -2- SYMBOL ICC VIO IB AV VOM THD SVR CS fT SR VNI TEST CONDITION SW ON SW OFF RS=10kΩ VIN RL=2kΩ RL=10kΩ f=1kHz,VO=5Vrms,GV=20dB f=1kHz GV=0dB GV=0dB,RL=2kΩ//100pF RS=1kΩ,BW=10Hz~30kHz,Flat 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 % µV/V dB MHz V/µs µVrms 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.
