Overview
The FOD2711A is an optically isolated amplifier consisting of a precision programmable shunt reference and an optocoupler. It features a phototransistor output with one channel. The device operates within a temperature range of -40°C to +85°C. Key electrical parameters include an insulation voltage of 5000 Vrms, a forward voltage (Vf) of 1.5 V, and a bandwidth of 10 kHz. It is available in PDIP-8 and MDIP-8 packages for through-hole or surface-mount installation.
Feature Summary
- Integrates a precision programmable shunt reference with an optocoupler for isolated error amplification
- Provides high-voltage isolation capability between input and output circuits
- Utilizes a phototransistor output stage for signal transmission
Applications
- Isolated error amplifier circuits
- Power supply feedback loops
- Industrial control systems requiring galvanic isolation
Procurement Notes
Verify the specific package variant required, as the FOD2711A series includes both PDIP-8 and MDIP-8 options with different mounting styles. Confirm that the 5000 Vrms insulation rating meets the safety requirements of the target application. Ensure the operating temperature range of -40°C to +85°C aligns with environmental conditions. Check datasheet specifications for current transfer ratio and bandwidth constraints before finalizing component selection.
Selection Notes
Select this component when a combined reference and isolation solution is needed for error sensing. The integrated AZ431L reference simplifies circuit design by reducing external component count. Consider the 10 kHz bandwidth limitation for high-speed applications. Verify compatibility with the system's voltage levels and isolation standards. The choice between DIP and MDIP packaging depends on the board layout and assembly method.
Part Context
The FOD2711A belongs to onsemi's family of optically isolated amplifiers. It combines the functionality of a voltage reference with optical isolation, targeting applications where precise error detection across isolation barriers is critical. This integration distinguishes it from standard optocouplers or standalone references.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter equivalence before replacing.
