ADM2867EBRNZ-RL7
Single Transmitter/Receiver RS-422/RS-485 28-Pin SOIC W T/R
Analog DevicesThe ADM2867E/ADM2561E, from Analog Devices, are 5.7 kV and 3 kV rms 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 ±12 kV contact and ±15 kV air IEC61000-4-2 ESD protection on the RS-485 A, B, Y, and Z pins. The devices also features 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.
Key Features and Benefits
- • Class B radiated Emissions on a 2 layer PCB reduces design time and reduces material costs
- • Cable invert smart feature reduce end system install & debug time - allows customer's customer to easily correct installation-based connection errors
- • IEC 61000-4-2 ESD and 5.7kV reinforced iCoupler digital isolation with > 8mm creepage and clearance maintain signal integrity in the harshest of environments with the trusted safety of iCoupler digital isolation
Applications
- • Industrial Automation / PLC: IEC ESD, Class B Radiated Emissions, isoPower, Cable Invert, digital isolation
- • Communications: Isolation, EMC – surge, Cable Invert, Robustness
- • Building and Infrastructure: IEC ESD, Radiated Emissions Class B
- • Aerospace and Defense: EP required 105 C Temp, low radiated emissions
