INTEGRAL IL4558D

TECHNICAL DATA
IL4558
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
• Gain and phase math between amplifiers

This device contains protection circuitry to guard against damage due to high static voltages or electric
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, VIN and VOUT should be constrained to the range
GND≤(VIN or VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC).
Unused outputs must be left open.
