ADM2795EARWZ

ADM2795E is a 5KV rms signal isolated RS-485 transceiver that features up to ±42V of AC/DC peak bus overvoltage fault protection on the RS-485 bus pins. The device integrates Analog Devices, Inc., icoupler® technology to combine a 3-channel isolator, RS-485 transceiver, and IEC electromagnetic compatibility (EMC) transient protection in a single package. This RS-485/RS-422 transceiver that integrates IEC 61000-4-5 level 4 surge protection, allowing up to ±4KV protection on the RS-485 bus pins (A and B). The device has IEC 61000-4-4 level 4 EFT protection up to ±2KV and IEC 61000-4-2 level 4 ESD protection on the bus pins, allowing this device to withstand up to ±15KV on the transceiver interface pins without latching up. Typical applications are heating, ventilation, and air conditioning (HVAC) networks, industrial field buses, building automation, utility networks.

• Fully TIA/EIA RS-485/RS-422 compliant when operated over a 3 V to 5.5 V VDD2 power supply
• IEC 61000-4-6 conducted radio frequency (RF) immunity (10V/m rms)
• Robust noise immunity (tested to the IEC 62132-4 standard)
