DESCRIPTION
The FOD2712 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 FOD2712, 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 compact 8-pin small outline package.
