Overview
The FOD2711ASD is an optically isolated amplifier featuring a precision programmable shunt reference and a phototransistor output. It provides 5000Vrms isolation voltage with a single channel. The device operates within a temperature range of -40°C to +85°C in an 8-SMD package. Key electrical parameters include a forward voltage of 1.5V, a collector-emitter saturation voltage of 400mV, and a current transfer ratio ranging from 100% to 200% at 10mA input current.
Feature Summary
- Integrates RC431A precision programmable shunt reference for error amplification
- Provides high-voltage galvanic isolation between input and output circuits
- Utilizes phototransistor output stage for signal transmission
Applications
- Switching power supply feedback loops
- Isolated error amplifier circuits
- Voltage regulation systems requiring optical isolation
Procurement Notes
Verify the manufacturer designation, as Fairchild Semiconductor assets were acquired by ON Semiconductor. Confirm the specific suffix 'ASD' corresponds to the surface-mount 8-pin configuration. Ensure compliance with RoHS directives if required for the target assembly process. Cross-reference datasheets from both original Fairchild and current ON Semiconductor sources to confirm pinout and electrical specifications remain consistent across production eras.
Selection Notes
Select this component when a combined error amplifier and optocoupler solution is needed to reduce board space. The integrated shunt reference simplifies circuit design compared to discrete implementations. Consider the 8-SMD package constraints and thermal management requirements for the operating temperature range. Verify that the 5000Vrms isolation rating meets the safety standards of the application environment.
Part Context
This part belongs to the FOD2711 series of optically isolated amplifiers. It combines the functionality of a precision voltage reference with an optocoupler to create a compact isolation solution. The series is commonly used in applications requiring accurate voltage monitoring across isolation barriers without complex external components.
Replacement Considerations
Check for equivalents such as FOD2711AS or FOD2711A depending on package requirements. Verify pin compatibility before substitution. Review updated datasheets from ON Semiconductor for any specification changes following the acquisition of Fairchild's semiconductor business.
