Overview
The FOD2711AV is a single-channel optically isolated amplifier manufactured by Fairchild Semiconductor. It integrates an RC431A precision programmable shunt reference with a phototransistor output optocoupler in an 8-pin DIP package. The device provides high current transfer efficiency, featuring a minimum CTR of 100% and a maximum CTR of 200% at a forward current of 10 mA. It offers a bandwidth of 10 kHz and supports an operating temperature range from -40°C to +85°C. The unit ensures robust isolation with a rated voltage of 5000 Vrms.
Feature Summary
- Integrates a precision programmable shunt reference with a phototransistor for error amplification
- Provides high current transfer ratio efficiency for signal integrity
- Offers reliable electrical isolation between input and output circuits
Applications
- Switching power supply feedback loops
- Isolated error amplification circuits
- Voltage regulation systems requiring galvanic isolation
Procurement Notes
Verify the manufacturer designation on the component marking, as this part was originally produced by Fairchild Semiconductor and later transitioned to ON Semiconductor. Ensure the datasheet version matches the specific production lot requirements. Confirm that the 8-pin DIP package dimensions align with the target PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate that the thermal characteristics meet the system's operational temperature constraints.
Selection Notes
Select this component when a combined error amplifier and isolation stage is required in a compact form factor. The integrated shunt reference simplifies circuit design by reducing external component count. Consider the 10 kHz bandwidth limitation for high-frequency applications. The through-hole DIP package is suitable for prototyping or standard industrial enclosures. Evaluate the 5000 Vrms isolation rating against the system's safety requirements.
Part Context
This device belongs to the FOD2711 series of optically isolated amplifiers. It is functionally equivalent to other models in the family that combine a shunt reference with an optocoupler. The series is designed for applications needing precise voltage monitoring across isolated boundaries. Manufacturing ownership transferred from Fairchild Semiconductor to ON Semiconductor following corporate restructuring.
Replacement Considerations
Check for direct equivalents such as the FOD2711AS or FOD2711AV from ON Semiconductor. Verify pinout compatibility before substitution. Ensure the replacement maintains the same isolation voltage and current transfer ratio specifications.
