NJU7051/52/54 LOW INPUT OFFSET VOLTAGE C-MOS OPERATIONAL AMPLIFIER ■ GENERAL DESCRIPTION The NJU7051,52 and 54 are single,dual and quad C-MOS Operational Amplifiers operated on a single-power-supply,low voltage and low operating current. The input offset voltage is lower than 2mV,and the input bias current is as low as less than 1pA,consequently the very small signal around the ground level can be amplified. The minimum operating voltage is 1V and the output stage permits output signal to swing between both of the supply rails. Furthermore,the operating current is also as low as 15µA ( typ ) per circuit,therefore it can be applied especially to battery operated items. ■ FEATURES ● Single-Power-Supply ● Low Input Offset Voltage ( VIO=2mV max ) ● Wide Operating Voltage ( VDD=1~16V ) ● Wide Output Swing Range ( VOM=2.94V typ. @ VDD=3V ) ● Low Operating Current ( 15µA/circuit ) ● Low Bias Current ( IIB=1pA typ. ) ● Internal Compensation Capacitor ● External Offset Null Adjustment ( Only NJU7051 ) ● Package Outline DIP/DMP/SSOP8 ( NJU7051 ) DIP/DMP8 ( NJU7052 ) DIP/DMP/SSOP14 ( NJU7054 ) ● C-MOS Technology ■ PACKAGE OUTLINE NJU7051D NJU7052D NJU7054D NJU7051V NJU7051M NJU7052M NJU7054M NJU7054V ■ PIN CONFIGURATION NJU7051D NJU7051M NJU7051V NJU7052D NJU7052M NJU7054D NJU7054M NJU7054V Ver.2003-03-18 -1- NJU7051/52/54 ■ EQUIVALENT CIRCUIT ‫ ٭‬IN1,IN2 are only for NJU7051 ( NJU7052/54 don’t have these terminals ). -2- Ver.2003-03-18 NJU7051/52/54 ■ ABSOLUTE MAXIMUM RATINGS ( Ta=25˚C ) PARAMETER Supply Voltage Differential Input Voltage Common Mode Input Voltage SYMBOL VDD VID VIC Power Dissipation PD Operating Temperature Range Storage Temperature Range Topr Tstg RATINGS 18 ± 18 ( note1 ) -0.3~18 ( DIP14 ) 700 ( DIP8 ) 500 ( DMP8,14 ) 300 ( SSOP8,14 ) 300 -20~+75 -40~+125 UNIT V V V mW ˚C ˚C ( note1 ) If the supply voltage ( VDD ) is less than 18V, the input voltage must not over the VDD level though 18V is limit specified. ■ ELECTRICAL CHARACTERISTICS ( Ta=25˚C,VDD=3V,RL=∞ ) PARAMETER Input Offset Voltage Input Offset Current Input Bias Current Input Impedance Large Signal Voltage Gain Input Common Mode Voltage Range Maximum Output Swing Voltage Common Mode Rejection Ratio Supply Voltage Rejection Ratio Operating Current/Circuit Slew Rate Unity Gain Bandwidth SYMBOL VIO IIO IIB RIN AV VICM VOM CMR SVR IDD SR Ft TEST CONDITION RS=50Ω RL=1MΩ AV=40dB,CL=10pF MIN. 80 0~2 2.90 60 60 - TYP. 1 1 1 90 2.94 70 70 15 0.05 0.1 MAX. 2 25 - UNIT mV pA pA TΩ dB V V dB dB µA V/µs MHz ■ OFFSET ADJUSTMENT CIRCUIT ( Only For NJU7051 ) [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
