DESCRIPTION
The FOD2711 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%.
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.
When using the FOD2711, 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.
The device comes in a 8-pin dip white package.
