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%.

Optocoupler, precision reference and error amplifier in single package.
2.5V reference.
CTR 100% to 200%.
5,000V RMS isolation.
UL approved E90700, Volume 2 CSA approval 1296837 VDE approval 40002463 BSI approval 8702, 8703.
Low temperature coefficient 50ppm/°C max.
FOD2741A: tolerance 0.5% FOD2741B: tolerance 1% FOD2741C: tolerance 2%.
