Analog Devices ADM2867E Isolated RS-485 Transceiver

Added to your shopping cart

Analog Devices ADM2867E Isolated RS-485 Transceivers are a 5.7kVrms signal and power isolated RS-485 transceivers. The devices pass radiated emissions testing to the EN55032 Class B standard with margin on a 2-layer printed circuit board (PCB) using two small external 0402 ferrites on isolated power and ground pins. The device features an integrated, low electromagnetic interference (EMI), isolated dc-to-dc converter, which eliminates the need for an external isolated power supply. The isolation barrier provides immunity to system-level electromagnetic compatibility (EMC) standards. The family of isolator devices features ±12kV contact and ±15kV air IEC61000-4-2 ESD protection on the RS-485 A, B, Y, and Z pins. The devices also feature cable invert pins, allowing the user to quickly correct reversed cable connection on the A, B, Y, and Z bus pins while maintaining full receiver fail-safe performance.
