LOW-POWER TINY SINGLE C-MOS OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJU7011,12 and 13 are single C-MOS operational
amplifiers operated on a single-power-supply, low voltage and low
operating current.
The input bias current is as low as than 1pA,consequently 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 SOT−23−5,
therefore it can be especially applied to portable items.
■ FEATURES ■ PIN CONFIGURATION
● Single-Power-Supply
● Wide Operating Voltage ( VDD=1~5.5V )

PARAMETER SYMBOL RATINGS UNIT
Supply Voltage VDD 6.5 V
Differential Input Voltage VID ± 6.5 ( note1 ) V
Common Mode Input Voltage VIC -0.3~6.5 V
Power Dissipation PD 200 mW
Operating Temperature Range Topr -40~+85 ˚C
Storage Temperature Range Tstg -55~+125 ˚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.
