| NJU7019 LOW-VOLTAGE OPERATION DUAL C-MOS OPERATIONAL AMPLIFIER GENERAL DESCRIPTION The NJU7019 is a low voltage single-power-supply and low operating current dual C-MOS operational amplifier. 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 signals to swing between both of the supply rails. Furthermore, the NJU7019 is packaged with a various small one therefore it can be especially applied to portable items. FEATURES Single-Power-Supply Wide Operating Voltage ( VDD=1~5.5V ) Wide Output Swing Range ( VOM=2.9V min. @ 3.0V ) Low Operating Current ( IDD=20A typ./circuit ) Low Bias Current ( IIB=1pA typ. ) Compensation Capacitor Incorporated C-MOS Technology Package Outline VSP8 EQUIVALENT CIRCUIT PACKAGE OUTLINE NJU7019R PIN CONFIGURATION Ver.2003-03-18 -1- NJU7019 ABSOLUTE MAXIMUM RATINGS ( Ta=25C ) PARAMETER Supply Voltage Differential Input Voltage Common Mode Input Voltage Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL VIN VID VIC PD Topr Tstg RATINGS 7 7 ( note1 ) -0.3~7 ( VSP8 ) 320 -40~+85 -55~+125 UNIT V V V mW C C ( note1 ) If the supply voltage ( VDD ) is less than 7V, the input voltage must not over the VDD level though 7V is limit specified. ( note2 ) Decoupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit.
