The ADM2795E is a 5 kV rms signal isolated RS-485 transceiver that features up to ±42 V 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. The ADM2795E is a RS-485/RS-422 transceiver that integrates IEC 61000-4-5 Level 4 surge protection, allowing up to ±4 kV protection on the RS-485 bus pins (A and B). The device has IEC 61000-4-4 Level 4 EFT protection up to ±2 kV and IEC 61000-4-2 Level 4 ESD protection on the bus pins, allowing this device to withstand up to ±15 kV on the transceiver interface pins without latching up. This device has an extended common-mode input range of ±25 V to improve data communication reliability in noisy environments. The ADM2795E is capable of operating over wide power supply ranges, with a 1.7 V to 5.5 V VDD1 power supply range, allowing interfacing to low voltage logic supplies. The ADM2795E is also fully TIA/EIA RS-485/RS-422 compliant when operated over a 3 V to 5.5 V VDD2 power supply. The device is fully characterized over an extended operating temperature range of −40°C to +125°C, and is available in a 16-lead, wide-body SOIC package.

Evaluation Kits (1)
Use the EVAL-ADM2795EEBZ to easily evaluate the ADM2795E 5 kV rms signal isolated RS-485/RS-422 transceiver with Level 4 IEC EMC and 24 V supply fault protection. The EVAL-ADM2795EEBZ evaluation board is easily configured through jumper connections and screw terminal blocks for signal and power connections. The EVAL-ADM2795EEBZ can be powered with either a 9 V battery or a standard configurable bench top power supply. An on-board trimmer potentiometer and an on- board regulator circuit on both VDD1 and VDD2 allow easy power configuration when connected to a 9 V battery.
For −55°C to +125°C temperature ranges, use the EVAL-ADM2795EEPBZ. EVAL-ADM2795EEPBZ shares the same evaluation platform features and to support defense and aerospace applications (AQEC standard and DO-160G ESD & EMC).
