Manufacturer: Fairchild (now onsemi)

Overview: FOD2742A, FOD2742B, FOD2742C — Optically Isolated Error Amplifier FOD2742A, FOD2742B, FOD2742C Optically Isolated Error Amplifier April.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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 es in 3 grades of reference voltage tolerance = 2%, 1%, and 0.5%.
