Overview
The FOD2711ASDV is an optically isolated error amplifier manufactured by Fairchild Semiconductor. It integrates a precision programmable shunt reference with a phototransistor output optocoupler in an 8-SMD package. The device provides galvanic isolation up to 5000 Vrms, supporting high-voltage isolation applications. Key electrical parameters include a maximum collector current of 50 mA, a bandwidth of 10 kHz, and a reference voltage of 1.24 V. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a precision programmable shunt reference with a phototransistor output for closed-loop control
- Provides high-voltage galvanic isolation between input and output circuits
- Designed for use as an optically isolated error amplifier in power supply feedback loops
Applications
- Switching power supply feedback loops
- High-voltage isolation interfaces
- Closed-loop control systems requiring precise voltage referencing
Procurement Notes
Verify the manufacturer origin, as ON Semiconductor acquired Fairchild's semiconductor business. Ensure the part number suffix matches the required surface-mount package configuration. Confirm compliance with RoHS directives and check for specific lot traceability requirements relevant to your manufacturing standards before finalizing procurement orders.
Selection Notes
Select this component when a combined error amplifier and isolation barrier are needed in a compact surface-mount form factor. Consider the 5000 Vrms isolation rating for safety-critical designs. Evaluate the 10 kHz bandwidth against the switching frequency of the target application to ensure adequate response time without instability.
Part Context
This device belongs to the FOD2711 family of optically isolated amplifiers. It is functionally similar to the through-hole FOD2711A but utilizes an 8-SMD package suitable for automated surface-mount assembly processes. The integration simplifies design by combining the reference and isolation stages into a single component.
Replacement Considerations
The FOD2711A is a pin-compatible through-hole alternative from the same family. Verify package type compatibility (SMD vs. DIP) and confirm that the isolation voltage and current transfer ratio specifications meet the original design requirements.
