The ADM2761E/ADM2763E are 500 kbps, 5.7 kVRMS, signal isolated RS-485 transceivers that pass radiated emissions testing to the EN 55032, Class B standard with margin on a 2-layer printed circuit board (PCB). These devices are compliant to the RS-485 and RS-422 communication standards. The ADM2761E/ ADM2763E isolation barrier provides robust system level immunity to IEC 61000-4-x system level electromagnetic compatibility (EMC) standards. The devices are suitable for applications that require insulation against working voltages of 1060 VRMS and 1500 VDC for the lifetime of the device.
The devices are protected against ≥±12 kV contact and ≥±15 kV air IEC 61000-4-2 electrostatic discharge (ESD) events on the RS-485 A, B, Y, and Z pins. The ADM2763E features a receiver cable invert pin to allow quick correction of the reversed cable connection on the A and B receiver bus pins while maintaining full receiver fail-safe performance.
These devices are optimized for low speed over long cable runs and have a maximum data rate of 500 kbps. The high differential output voltage makes these devices suitable for PROFIBUS® nodes when powered with 5 V on the VDD2 supply. The VDD1 primary supply and VDD2 isolated supply both support a wide range of voltages (1.7 V to 5.5 V and 3.0 V to 5.5 V, respectively). Half-duplex and full duplex device options are available in the industry standard 16-lead, wide body, standard SOIC_W package with 8.2 mm creepage and clearance.
Applications
- Solar inverters
- Electrical test and measurement
- Heating, ventilation, and air-conditioning (HVAC) networks
- Industrial field buses
- Building automation
