Optocoupler/LED/nixie tube/photoelectric device

The FOD2711A opto-isolated amplifier includes the popular AZ431L precision programmable shunt voltage reference and optocoupler. The optocoupler is a gallium arsenide (GaAs) light-emitting diode optically coupled to a silicon phototransistor. The reference voltage tolerance is 1%. The range of current transfer ratio (CTR) is 100%-200%. 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 FOD2712A, 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 a compact 8-pin small encapsulation.
