FAIRCHILD SEMICONDUCTOR OPTICALLY ISOLATED ERROR AMPLIFIER Page 1 of 15 FOD2741A FOD2741B FOD2741C handbook
The FOD2741 series combines a precision programmable shunt reference with an optocoupler in a single 8‑pin DIP package. It is intended for use as an error amplifier, reference voltage source, and optocoupler in isolated AC‑to‑DC power supplies and DC‑to‑DC converters.
Key features include a 2.5 V reference, current transfer ratio of 100 %–200 %, 5000 Vrms isolation, 50 kHz bandwidth, and a low temperature coefficient of 50 ppm/°C. The datasheet lists absolute maximum ratings, electrical characteristics, and typical performance curves to aid designers.
