NJU7071/72/74 LOW INPUT OFFSET VOLTAGE C-MOS OPERATIONAL AMPLIFIER ■ GENERAL DESCRIPTION The NJU7071,72 and 74 are single, dual and quad C-MOS Operational Amplifiers operated on a single-power-supply 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 single around the ground level can be amplified. The minimum operating voltage is 5V and the output stage permits output signal to swing between both of the supply rails. Furthermore, the operating current is also as low as 0.6mA ( 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=5~16V ) ● Wide Output Swing Range ( VOM≥9.98V typ. @ VDD=10V ) ● Low Operating Current ( 0.6mA/circuit typ. ) ● Low Bias Current ( IIB=1pA typ. ) ● Internal Compensation Capacitor ● External Offset Null Adjustment ( Only NJU7071 ) ● Package Outline DIP/DMP/SSOP8 ( NJU7071 ) DIP/DMP8 ( NJU7072 ) DIP/DMP/SSOP14 ( NJU7074 ) ● C-MOS Technology ■ PIN CONFIGURATION ■ PACKAGE OUTLINE NJU7071D NJU7072D NJU7071M NJU7072M NJU7074D NJU7074M NJU7071V NJU7074V NJU7071D NJU7071M NJU7071V NJU7072D NJU7072M NJU7074D NJU7074M NJU7074V Ver.2003-03-18 -1- NJU7071/72/74 ■ EQUIVALENT CIRCUIT ‫٭‬The terminals IN1, IN2 are only for NJU7071 ( NJU7072/74 don’t have these terminals ). -2- Ver.2003-03-18 NJU7071/72/74 ■ ABSOLUTE MAXIMUM RATINGS ( Ta=25˚C ) PARAMETER Supply Voltage Differential Input Voltage Common Mode Input Voltage Power Dissipation SYMBOL VDD VID VIC PD Topr Tstg RATINGS 18 ± 18 ( note1 ) -0.3~18 ( DIP8 ) 500 ( DIP14 ) 700 ( DMP8,14 ) 300 ( SSOP8 ) 250 ( SSOP14 ) 300 -20~+75 -40~+125 UNIT V V mA mW Operating Temperature Range Storage Temperature Range ˚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=10V,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 MIN. 80 0~9 9.80 60 60 TYP. 1 1 1 95 9.98 75 75 0.6 1.1 1.0 MAX. 2 1.2 UNIT mV pA pA TΩ dB V V dB dB mA V/µs MHz RL=1MΩ AV=40dB,CL=10pF ■ OFFSET ADJUSTMENT CIRCUIT ( Only For NJU7071 ) [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
