Product Details

Based on the Analog Devices, Inc., iCoupler® technology, the ADM3053 and the ADM2582E integrate logic side, signal isolation channels with an Analog Devices isoPower® dc-to-dc converter to provide regulated, isolated power. The EVAL-2LCANRS485EBZ evaluation board demonstrates best practices for layout on a 2-layer printed circuit board (PCB). This board has been tested according to EN 55032 and has passed Class A limits.

The EVAL-2LCANRS485EBZ, as shipped, is populated with the ADM3053 signal and power isolated transceiver for controller area network (CAN) and the ADM2582E signal and isolated transceiver for RS-485. The EVAL-2LCANRS485EBZ allows access to all of the input and output functions of both transceivers.

While the ADM3053 and the ADM2582E are not directly pin-compatible, the EVAL-2LCANRS485EBZ can be alternately populated with either two ADM3053 devices or two ADM2582E devices.

Full specifications on the ADM3053 and the ADM2582E can be found in the ADM3053 and the ADM2582E data sheets, available from Analog Devices, and must be consulted in conjunction with this user guide when using the EVAL-2LCANRS485EBZ.

Product Details

The ADM2582E power and signal isolated RS-485 transceivers have two options for easy evaluation: the EVAL-ADM2582EEBZ 4-Layer EN55022 Class B Radiated Emissions Compliant Evaluation Board or the EVAL-ADM2582EEMIZ 2-Layer EN55022 Class A Radiated Emissions Compliant Evaluation Board. Both evaluation boards options are populated with an ADM2582E 20-lead wide-body SOIC component.

The EVAL-ADM2582EEBZ 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 4 layer board layout was generated using the guidelines provided in the AN-0971 Application Note, Recommendations for Control of Radiated Emissions with isoPower Devices. The EVAL-ADM2582EEBZ evaluation board was tested at an independent test facility. The evaluation board passed the IEC 61000-4-5 surge testing up to 2 kV.

The EVAL-ADM2582EEMIZ is designed to reduce emissions generated by the high frequency switching elements used by the isoPower® technology to transfer power through the ADM2582E/ADM2587E integrated transformer. The 2 layer board layout is generated using the guidelines provided in the AN-1349 Application Note, PCB Implementation Guidelines to Minimize Radiated Emissions on the ADM2582E/ADM2587E RS-485/RS-422 Transceivers. The EVAL-ADM2582EEMIZ evaluation boards are tested and certified to pass EN55022 Class A.
