製品概要
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.
