Optically Isolated Error Amplifier  
Features  
Description  
Optocoupler, precision reference and error amplifier in  
The FOD2741 Optically Isolated Amplifier consists of the  
popular KA431 precision programmable shunt reference  
and an optocoupler. The optocoupler is a gallium ars-  
enide (GaAs) light emitting diode optically coupled to a  
silicon phototransistor. It comes in 3 grades of reference  
voltage tolerance = 2%, 1%, and 0.5%.  
single package  
2.5V reference  
CTR 100% to 200%  
5,000V RMS isolation  
UL approved E90700, Volume 2  
CSA approval 1296837  
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 iso-  
lated AC to DC power supplies and DC/DC converters.  
VDE approval 40002463  
BSI approval 8702, 8703  
Low temperature coefficient 50ppm/°C max.  
FOD2741A: tolerance 0.5%  
FOD2741B: tolerance 1%  
FOD2741C: tolerance 2%  
When using the FOD2741, power supply designers can  
reduce the component count and save space in tightly  
packaged designs. The tight tolerance reference elimi-  
nates the need for adjustments in many applications.  
The device comes in a 8-pin dip white package.
