Analog Devices / Maxim Integrated MAXM22510 / MAXM22511 Transceiver Modules

Analog Devices MAXM22510 / MAXM22511 RS-485/RS-422 Transceiver Modules provide 2500VRMS (60s) of galvanic isolation between the cable-side (RS-485/RS-422 driver/receiver side) and the UART-side of the device. An integrated DC-DC converter powers the cable side of the module. No external components are required for the Analog Devices MAXM22510 / MAXM22511. Isolation improves communication by breaking ground loops and reduces noise when there are significant differences in ground potential between ports. These devices allow for robust communication up to 500kpbs (MAXM22510) and 25Mbps (MAXM22511).
