ADI launches the first RS-485 transceiver that strictly complies with IEC surge standards

Beijing November 3, 2016 / US News / - Analog Devices, Inc. (ADI) recently announced the introduction of the industry's first batch of RS-485 transceiver ADM2795E and ADM3095E through the 4th level EMC surge protection, The demand for external transient voltage surge suppression devices will not be present. Current Isolated ADM2795E (using Adi iCoupler® magnetic isolation technology) and non-separation ADM3095E saves space and components, shortening time, and maximizing compliance issues. Integrated fault protection provided by these devices prevents potential destructive voltages from damaging communication interfaces to avoid causing circuit failure, surge, electrostatic discharge (ESD) and wiring errors. ADI launches the first RS-485 transceiver that strictly complies with IEC surge standards Because these new RS-485 transceivers have the necessary approval, designers do not need to perform separate design, test, verification, and formal application compliance certification. Also, there is no need to use an external protective element, so there is no need to match these discrete devices according to the specific RS-485 transceiver selected by the user. For the case of RS-485 port density, it can simplify the BOM and space occupation on board. The ADM2795E and ADM3095E RS-485 transceivers complies with IEC61000-4-5 level 4 surge protection requirements, industrial IEC immunity standards (radiation, conductive and magnetic field immunity) and for ESD, electricity transients (EFT) and waves Yang's EMC protection requirements. The two devices are in accordance with the entire 3 V to 5.5 V power supply, which is compliant with TIA / EIA RS-485 / RS-422 specification. In addition, it also provides an evaluation board, IBIS model, security, and compliance certificate, and RS-485 transceiver video and application notes, greatly simplifying the design import process. Important specifications include: .5 kV RMS isolation RS-485 / RS-422 transceiver (ADM2795E) . IEC 61000-4-x Certified Isolation Gate Anti - Distortion (ADM2795E) High common model transient refractory: >75 kV / μs (ADM2795E) .RS-485 A, B bus pin provides certified level 4 EMC protection . IEC61000-4-5 Surge protection (+/- 4 kV) .Iec61000-4-4 EFT protection (+/- 2 kV) . IEC61000-4-2 ESD protection .8 kV contact discharge . + / - 15 kV air gap .IEC61000-4-6 Biography RF Anti - Distance (10 V / M RMS) .RS-485 A, B pin body model (HBM) ESD > + / - 30 kV .RS-485 bus pin provides +/- 42 V AC / DC peak fault protection The extended common mode input voltage range is -25 V to +25 V Compliance with TIA / EIA RS-485 / RS-422 throughout the power supply range and temperature up to 125 degrees Celsius Search for "Love Bo.com" to pay attention, daily update development board, intelligent hardware, open source hardware, activities, etc., you can make you master.
