Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

email any questions regarding the system integration to

Description
The FOD2711A Optically Isolated Amplifier consists of
the popular AZ431L precision programmable shunt ref-
erence and an optocoupler. The optocoupler is a gallium
arsenide (GaAs) light emitting diode optically coupled to
a silicon phototransistor. The reference voltage toler-
ance 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 FOD2711A, power supply designers can
reduce the component count and save space in tightly
packaged designs. The tight tolerance reference elimi-
nates the need for adjustments in many applications.
