FOD2711ATV

Overview

The FOD2711ATV is an optically isolated error amplifier integrating a precision programmable shunt reference and an optocoupler in a single package. It features a phototransistor output with a bandwidth of 10 kHz and operates within a temperature range of -40°C to +85°C. The device provides 5000 Vrms isolation voltage and has a forward voltage of 1.5 V. Key electrical parameters include a current transfer ratio of 100% to 200%, a maximum collector current of 50 mA, and a reference voltage of 1.24 V. It is housed in a PDIP-8 through-hole package.

Feature Summary

• Integrates a precision programmable shunt reference with an optocoupler for compact error amplification
• Provides high-voltage isolation between input and output circuits
• Delivers stable reference voltage for feedback loop control

Applications

• Switching power supply error amplification
• Isolated feedback loops in AC/DC converters
• Battery management system monitoring

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor assets were acquired by onsemi. Confirm the specific suffix 'TV' corresponds to the tape and reel packaging variant if required for automated assembly. Ensure the component meets RoHS compliance standards applicable to your region. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match your design requirements before finalizing procurement.

Selection Notes

Select this component when a combined reference and isolation stage is needed to reduce board space. The integrated shunt reference eliminates the need for external voltage references. Consider the 10 kHz bandwidth limitation for high-frequency switching applications. The PDIP-8 package is suitable for prototyping or low-volume production where surface mount technology is not mandatory.

Part Context

This part belongs to the FOD2711 series of optically isolated amplifiers. It is functionally similar to other integrated error amplifier optocouplers but distinguishes itself through the specific integration of the AZ431L or RC431A reference core. The 'TV' suffix typically denotes a specific packaging configuration, such as tape and reel, differing from standard tube packaging found in variants like FOD2711A.

Replacement Considerations
