OPTICALLY ISOLATED  
ERROR AMPLIFIER  
FOD2712  
DESCRIPTION  
PACKAGE DIMENSIONS  
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 phototransistor. The  
reference voltage tolerance is 1%. The current  
transfer ratio (CTR) ranges from 100% to 200%.  
0.164 (4.16)  
0.144 (3.66)  
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.

0.182 (4.63)  
When using the FOD2712, 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.
