The FOD2741 opto-isolated amplifier includes the popular KA431 precision programmable shunt voltage reference and optocoupler. The optocoupler is a gallium arsenide (GaAs) light-emitting diode optically coupled to a silicon phototransistor. It has 3 levels of reference voltage with tolerance = 2%, 1% and 0.5%. The range of current transfer ratio (CTR) is 100%-200%. It also has an outstanding temperature coefficient of 50 ppm/°C. It is primarily used as an error amplifier/reference voltage/optocoupler in isolated AC-to-DC power supplies and DC/DC converters. When using the FOD2741, power supply designers can reduce the number of components and save space in tight encapsulation designs. Tight tolerance references make adjustments unnecessary in many applications. The device features an 8-pin DIP white encapsulation.
