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. FEATURES Operating Voltage: Input/Output Full-Swing High Output Current: Input Offset Voltage: Wide Input Common Mode Voltage Range: Operating Current: High Input Impedance: Low Input Bias Current: Ground Sensing Tiny Package: PIN CONFIGURATION PACKAGE OUTLINE

(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: PD" in which power dissipation in IC is shown by the absolute maximum rating. o Refer to following Figure 1 and Figure 2 for a permissible loss when ambient temperature (Ta) is Ta25 C.
