Features
Optocoupler, precision reference and error amplifier in
Description
The FOD2742 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 comes in 3 grades of
reference voltage tolerance = 2%, 1%, and 0.5%.
The Current Transfer Ratio (CTR) ranges from 100% to
200%. It also has an outstanding temperature coefficient
of 50 ppm/°C. 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 FOD2742, 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 small outline
package.
