Analog Devices Inc. ADM2761E & ADM2763E RS-485 Transceivers
Analog Devices Inc. ADM2761E and ADM2763E Transceivers are 500kbps, 5.7kVRMS, signal isolated RS-485 transceivers that pass radiated emissions which test the EN 55032, Class B standard with margin. These transceivers are compliant with the RS-485 and RS-422 communication standards. The ADM2761E and ADM2763E Transceivers are optimized for low speed over long cable runs and have a maximum data rate of 500kbps. These transceivers feature an isolation barrier that provides robust system-level immunity to IEC 61000-4-x system-level Electromagnetic Compatibility (EMC) standards. The ADM2763E transceivers feature a receiver cable invert pin to quickly correct the reversed cable connection on the A and B receiver bus pins.
The Analog Devices Inc. ADM2761E and ADM2763E Transceivers operate at 1.7V to 5.5V and 3.0V to 5.5V input voltage ranges on VDD1 and VDD2 supply voltages, respectively, within a -40°C to +125°C temperature range. The ADM2761E and ADM2763E Transceivers offer half-duplex and full-duplex device options in the industry standard. These transceivers come in a 16-lead, wide-body, standard SOIC_W package with 8.3mm creepage and clearance. The high differential output voltage of the transceivers makes them suitable for PROFIBUS® nodes when powered with 5V on the VDD2 supply. Applications include solar inverters, electrical test/measurement, heating/ventilation/air conditioning (HVAC) networks, industrial field buses, and building automation.
