Evaluation Board for the ADM2682E/ADM2687E 5 kV rms Signal and  
Power Isolated RS-485 Transceivers with 15 kV ESD Protection  
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.  
FEATURES  
5 kV rms power and signal isolated RS-485/RS-422 transceiver  
Convenient connections for power and signal through screw  
terminal blocks  
Configurable as half duplex or full duplex  
5 V or 3.3 V operation  
Easily configurable through jumper connections  
Test points for measuring all signals  
Layout optimized for emissions according to the AN-0971  
Application Note  
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.  
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.
