OPTICALLY ISOLATED ERROR AMPLIFIER

FOD2711

The FOD2711 Optically Isolated consists of the popular RC431A precision programmable shunt reference and an optocoupler. The optocoupler is a gallium arsenide GaAs light emitting diode optically coupled to a silicon phototransistor. The reference voltage tolerance is The current transfer ratio CTR ranges from 100% to

It is primarily intended for use as the error voltage/optocoupler function in isolated ac to dc power supplies and dc/dc converters.

When using the FOD2711, power supply designers can reduce the component count and
save space in tightly packaged designs. The tight tolerance reference eliminates the need
for adjustments in many applications.

The device comes in a 8-pin dip white package.
