EVALUATION KIT CONTENTS
EVAL–ADM2486EBZ
GENERAL DESCRIPTION
The EVAL-ADM2486EBZ allows the isolated
RS-485
transceivers to be easily and quickly evaluated. The evaluation
board allows all of the input and output functions to be exercised
without the need for external components.
differential bus transceiver is an integrated,
galvanically isolated component designed for bidirectional data
communication on multipoint bus transmission lines.
The device employs Analog Devices, Inc.,
i
Coupler® technology
to combine a 3-channel isolator, a three-state differential line
driver, and a differential input receiver into a single package.
The logic side of the device is powered with either a 5 V or a
3 V supply, and the bus side uses an isolated 5 V supply.
