ADM2682E/ADM2687E is a 5 kV rms signal and power isolated RS-485 transceiver with ±15 kV ESD from Analog Devices.
The ADM2682E and ADM2687E are fully integrated 5 kV rms signal‑and‑power isolated RS‑485/RS‑422 transceivers with +15 kV ESD protection. They combine iCoupler® isolation, a differential line driver, a receiver, and an isoPower® dc‑to‑dc converter in a 16‑lead wide‑body SOIC package. The devices operate from a single 5 V or 3.3 V supply and support half‑ or full‑duplex communication.
Key features include up to 16 Mbps data rate (ADM2682E), 500 kbps (ADM2687E), 5 kV rms isolation, high common‑mode transient immunity, thermal shutdown protection, and compliance with ANSI/TIA/EIA‑485‑A‑98 and IEC safety standards. The handbook provides detailed specifications, timing diagrams, pin descriptions, regulatory approvals, and PCB layout recommendations.
