OPTICALLY ISOLATED ERROR AMPLIFIER FOD2712
DESCRIPTION
The FOD2712 Optically Isolated Amplifier 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 photo
transistor.
The reference voltage tolerance is 1%.
The current transfer ratio (CTR) ranges from 100% to 200%.

It is primarily intended for use as the error amplifier/reference voltage/optocoupler function in isolated ac to dc power supplies and dc/dc converters.
When using the FOD2712, power supply designers can reduce the component count and save sp...
