NJU7044
Input/Output Full-Swing High Output Current
Quad C-MOS Operational Amplifier
■GENERAL
DESCRIPTION
The NJU7044 is a quad 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,
and very high input impedance.

(Note 1) For supply voltage less than 7V, the absolute maximum input voltage is equal to the supply voltage.
(Note 2) On the PCB " EIA/JEDEC (76.2x11.43x1.6mm, two layers, FR-4) "
(Note 3) On the PCB " EIA/JEDEC (76.2x11.43x1.6mm, four layers, FR-4) "
(Note 4) It individually takes the absolute value of the sink current and the source current of each output terminal, and it is assumed the sum total.
Calculation type: Iototal=|Ioport1|+|Ioport2|+|Ioport3|+|Ioport4|
(Note 5) Do not exceed "Power dissipation: P
