Input/Output Full-Swing High Output Current
Single C-MOS Operational Amplifier with Shutdown
GENERAL DESCRIPTION
The NJU7045 is a 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.
