NJU7094/95/96
LOW-POWER AND LOW-OFFSET-VOLTAGE
DUAL C-MOS OPERATIONAL AMPLIFIER
■
GENERAL DESCRIPTION
The NJU7094,95 and 96 are dual 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,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 a various small one
therefore it can be especially applied to portable items.

( note1 ) If the supply voltage ( V
DD
) is less than 7V, the input voltage must not over the V
DD
level though 7V is limit specified.
( note2 ) Decoupling capacitor should be connected between V
DD
and V
SS
for the stable operation.
