Overview
OPTICALLY ISOLATED ERROR AMPLIFIER FOD2741A DESCRIPTION The FOD2741 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%, 1%, and 0.
5%.
The Current Transfer Ratio (CTR) ranges from 100% to 200%.
It also has an outstanding temperature coefficient of 50 ppm/°C.
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 FOD2741, power supply designers can re...
