NJM2123M-TE1

NJM2123 DUAL OPERATIONAL AMPLIFIER WITH SWITCH ■ GENERAL DESCRIPTION The NJM2123 is a operational amplifier with analog switch ( 2 circuit of 2-input/1-output ). It is applicable to the audio part for Video ( VTR,LD…) and the Car-stereo. The NJM2123 has the same electrical characteristic of the NJM2112,and is low saturation output type. The mode of switch is improved from the current control type ( NJM2120:1 circuit of 2-input/1-output ) to the voltage control type.So,it is easy to use. ■ FEATURES ● Single Supply ● Operating Voltage ● Slew Rate ● Analog Switch Function ● Wide Unity Gain Bandwidth ● Package Outline ● Bipolar Technology ■ PACKAGE OUTLINE NJM2123D NJM2123M NJM2123V ( +4V~+20V ) ( 3V/µs typ. ) ( 10MHz typ. ) DIP16,DMP16,SSOP16 ■ PIN CONFIGURATION PIN FUNCTION 1.V + 9.GND 2.SW1 10.SW R 3.IN1 A +INPUT 11.IN2 B +INPUT 4.IN1 A –INPUT 12.IN2 B -INPUT 5.OUT1 13.OUT2 6.IN1 B –INPUT 14.IN2 A -INPUT 7.IN1 B +INPUT 15.IN2 A +INPUT 8.SW C 16.SW2 NJM2123D NJM2123M NJM2123V ■ EQUIVALENT CIRCUIT Ver.2003-03-17 -1- NJM2123 ■ ABSOLUTE MAXIMUM RATINGS ( Ta=25˚C ) PARAMETER Supply Voltage Differential Input Voltage Input Voltage Control Voltage SYMBOL + V VID VIC VCTR Power Dissipation PD Operating Temperature Range Storage Temperature Range Topr Tstg RATINGS 20 (± 10) ± 14 + 20(±10)note:Less than V (note) + 20(±10)note:Less than V ( DIP8 ) 700 ( DMP8 ) 300 ( SSOP8 ) 300 -30~+85 -40~+125 UNIT V V V V mW ˚C ˚C ■ ELECTRICAL CHARACTERISTICS ( V+=5V,Ta=25˚C ) PARAMETER Operating Current Input Offset Voltage Input Offset Current Input Bias Current Large Signal Voltage Gain Maximum Output Voltage Swing 1 Maximum Output Voltage Swing 2 Input Common Mode Voltage Range Common Mode Rejection Ratio Supply Voltage Rejection Ratio Slew Rate Gain Bandwidth Product Crosstalk Channel Separation Switch Threshold Voltage SYMBOL ICC VIO IIO IB AV VOM1 VOM2 VICM CMR SVR SR GB CT CS Vth TEST CONDITION VIN=2.5V,RL=∞ RS≤10kΩ RL≥10KΩ + V /V =±2.5V,RL≥2kΩ + V /V =±2.5V,RL≥10kΩ AV=1,VIN=2V~3V f=1kHz f=1kHz Internal Vth MIN. 60 ± 2.0 ± 2.3 1.5 60 60 2.0 TYP. 6.0 1.0 10 100 80 ± 2.2 ± 2.4 74 80 3 10 90 120 2.5 MAX. 8.0 6.0 200 300 4.0 3.0 UNIT mA mV nA nA dB V V V dB dB V/µs MHz dB dB V ( note1 ) Applied circuit voltage gain is desired to be operated within the range of 3dB to 30 dB. ( note2 ) Special care being required for input common mode voltage range and the oscillation due to the capacitive load when operating on voltage follower. ( note3 ) “Crosstalk” is defined about leak of signal on the same circuit. ( note4 ) “Channel Separation” is defined about leak of signal between 2 circuits. ( note5 ) Vth is possible to adjust by external parts. ( note6 ) Voltage for V--PIN has to be supplied earlier than V+-PIN in case of two supply voltage. -2- Ver.2003-03-17 NJM2123 ■ TYPICAL CHARACTERISTICS + In case of single supply voltage ( V =5V ) ■ SWITCHING MECHANISM The switch circuit of NJM2123 consist of comparators for switch and circuit for switch threshold voltage ( Vth ) due to establish threshold of comparator.Vth=Ii x Ri=2.5V in case of above Figure. Comparator selects INPUT ( A or B ) by compare of control voltage ( VCTR ) and threshold voltage ( Vth ) and control of operating current of Amp ( INPUT ). INPUT A is selected in case of VCTR>Vth and INPUT B is selected in case of VCTR2.5V ( Single supply ) Ver.2003-03-17 NJM2123 ■ TYPICAL CHARACTERISTICS Ver.2003-03-17 -5- NJM2123 ■ TYPICAL CHARACTERISTICS -6- Ver.2003-03-17 NJM2123 ■ TYPICAL CHARACTERISTICS Ver.2003-03-17 -7- NJM2123 ■ TYPICAL CHARACTERISTICS -8- Ver.2003-03-17 NJM2123 [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
