FOD2741B Overview
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 es in 3 grades of reference voltage tolerance = 2%, 1%, and 0.5%.
