LOW INPUT OFFSET VOLTAGE C-MOS OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJU7061,62 and 64 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 3V and the output stage
permits output signal to swing between both of the supply rails.
Furthermore, the operating current is also as low as 150µA
( 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=3~16V )
● Wide Output Swing Range ( VOM=9.98V typ. @ VDD=10V )
● Low Operating Current ( 150µA/circuit )
● Low Bias Current ( IIB=1pA typ. )
● Internal Compensation Capacitor
● External Offset Null Adjustment ( Only NJU7061 )
● Package Outline DIP/DMP/SSOP8 ( NJU7061 )
DIP/DMP8 ( NJU7062 )
DIP/DMP/SSOP14 ( NJU7064 )
