PACKAGE OUTLINE
The NJU7043 is a dual C-MOS operational amplifier
permitting a full-swing input and output in full-swing under
high load.
Based on C-MOS technology, there are excellent features
such as high output current, low current consumption, low
operating voltage.

(Note 1)
If the supply voltage (V
DD
) is less
than 5.5V, the input voltage must not
over the V
DD
level through 5.5V is limit
specified.
(Note 2)
Decoupling capacitor should be
connected between V
DD
and V

due
to the stabilized operation for the
circuit.
