Dual Operational Amplifiers
The IL4558 is dual general purpose operational amplifiers.
The high common-mode input voltage range and the absence of
latch-up make these amplifiers ideal for voltage follower application.
The devices are short circuit protected and the internal frequency
compensation ensures stability without external components.
•
Short-Circuit Protection
•
Wide common-mode and differential ranges
•
No frequency compensation required
•
Low power consumption
•
No latch-up
•
3 MHz unity gain bandwidth guaranteed
•

This device c ontains p rote ction ci rcuitr y to guard a gainst damage d ue to high st atic voltages or electr ic
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, V
GND≤(V

)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
and V

should be constrained to the range
OUT
CC
Unused outputs must be left open.
