Functional Description
This section explains how to implement the functions
found on the AM80A Performance Series. The pin
assignment shown in the diagram below does not apply to
AM80A-048L-050P25D033P30.
Remote Sense (+SENSE, -SENSE)
Connect the +SENSE and -SENSE pins of the AM80A
directly to the load to allow the module to compensate for
the voltage drop across the conductors carrying the load
current. If remote sensing is not required (for example if the
load is close to the module) the sense pins should be
connected directly to the module’s output pins to ensure
accurate regulation.
Note: If the sense leads fail open circuit, the module will
revert to local sense at the output pins. Incorrect
connection of sense leads may damage the module

Enable Control (ENABLE)
The enable pin is a TTL compatible input used to turn
the output of the module on or off. The module output
is enabled when the ENABLE pin is connected to -
SENSE or driven to a logic low of <0.7V (but not
negative).
The output is disabled when the enable pin is open or
driven to a logic high >2V. All monitoring and house-
keeping functions (including clock signals) continue to
operate normally.
