General Description

The ADM2867E is a 5.7 kV rms signal and power isolated full duplex RS-485 transceiver which passes radiated emissions testing to the EN55022 Class B standard with margin on a 2layer PCB using two small external 0402 ferrites on isolated power and ground pins.

The isolation barrier provides immunity to system level EMC standards.

The ADM2867E has ±12 kV contact, ±15 kV air IEC61000-4-2 ESD protection on RS-485 A, B, Y, and Z pins.
