GENERAL DESCRIPTION
The
ADM2582E/ADM2587E
the
ADM2582E
and
RS-422 transceivers. Screw terminal blocks provide convenient
connections for the power and signal connections. The evaluation
board is easily configured through jumper connections. The board
can be used in half-duplex or full-duplex configurations and has
a 120 Ω termination resistor fitted on the receiver input. The
evaluation board can be used with either the
device or the
ADM2587E
are enabled and disabled by jumper connections. Test points are
included on the power and signal lines on both sides of the
isolation barrier.
EN55022 RADIATED EMISSIONS
The
ADM2582E/ADM2587E
reduce emissions generated by the high frequency switching
elements used by the isoPower® technology to transfer power
through the
ADM2582E/ADM2587E
The layout of the evaluation board is generated using the guidelines
provided in the
AN-1349 Application
Guidelines to Minimize Radiated Emissions on the ADM2582E/
ADM2587E
RS-485/RS-422 Transceivers. The
ADM2582E
evaluation boards are tested and certified to pass
EN55022 Class B.
