EVALUATION KIT CONTENTS
EVAL-ADM2682EEBZ or EVAL-ADM2687EEBZ
GENERAL DESCRIPTION
The ADM2682E/ADM2687E evaluation board can be used for
easy evaluation of the ADM2682E and ADM2687E power and
signal isolated RS-485 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 ADM2682E 16 Mbps part or the ADM2687E
500 kbps part. The driver and receiver are enabled and disabled
by jumper connections. Test points are included on the power
and signal lines on both sides of the isolation barrier.
RADIATED EMISSIONS
The ADM2682E/ADM2687E evaluation board is designed to
reduce emissions generated by the high frequency switching
elements used by the isoPower® technology to transfer power
through its transformer. The layout of the evaluation board
was generated using the guidelines provided in the AN-0971
Application Note, Recommendations for Control of Radiated
Emissions with isoPower Devices.
