FOD2742A Datasheet (Fairchild Semiconductor) - Optically Isolated Error Amplifier

FOD2742A, Optically Isolated Error Amplifier

The FOD2742 Optically Isolated Amplifier consists of the popular KA431 precision programmable shunt reference and an optocoupler.

The optocoupler is a gallium arsenide (GaAs) light emitting diode optically coupled to a silicon phototransistor.

It comes in 3 grades of reference voltage tolerance = 2%
