| NJU7091A/92A/93A LOW-POEWR AND LOW-OFFSET-VOLTAGE TINY SINGLE C-MOS OPERATIONAL AMPLIFIER GENERAL DESCRIPTION The NJU7091A,92A and 93A are single 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 than 1pA,consenquently 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,this series is packaged with very small MTP-5,therefore it can be especially applied to portable items. FEATURES Single-Power-Supply Low Offset Voltage ( VIO=2mV max ) Wide Operating Voltage ( VDD=1~5.5V ) Wide Output Swing Range ( VOM=2.9V min. @ 3.0V ) Low Operating Current Low Bias Current ( IIB=1pA typ. ) Compensation Capacitor Incorporated Package Outline MTP5 C-MOS Technology LINE-UP ( Ta=25C,VDD=3.0V ) PARAMETER Operating Current Slew Rate Unity Gain Bandwidth NJU7091A 15 0.1 0.2 NJU7092A 80 1.0 1.0 NJU7093A 200 2.4 1.0 A V/s MHz UNIT ( typ ) ( typ ) ( typ ) PACKAGE OUTLINE NJU709XAF PIN CONFIGURATION EQUIVALENT CIRCUIT Ver.2003-03-18 -1- NJU7091A/92A/93A ABSOLUTE MAXIMUM RATINGS ( Ta=25C ) PARAMETER Supply Voltage Differential Input Voltage Common Mode Input Voltage Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL VDD VID VIC PD Topr Tstg RATINGS 6.5 6.5 ( note1 ) -0.3~6.5 200 -40~+85 -55~+125 UNIT V V V mW C C ( note1 ) If the supply voltage ( VDD ) is less than 6.5V, the input voltage must not over the VDD level though 6.5V is limit specified. ( note2 ) Decoupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit.
