OPTICALLY ISOLATED  
ERROR AMPLIFIER  
FOD2711  
DESCRIPTION  
The FOD2711 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 phototransistor. 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 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.
