2.5 kV Isolated RS-485 Transceivers with Integrated Transformer Driver ADM2482E/ADM2487E is a 500 kbps/16 Mbps 5 V or 3.3 V operation (VDD1) RS-485/RS-422 isolated transceivers with ±15 kV ESD protection, 256 nodes, true fail-safe receiver inputs, 2500 V rms isolation, 560 V peak, high common-mode transient immunity, thermal shutdown protection, operating temperature range -40°C to +85°C and wide-body 16-lead SOIC package.
The ADM2482E and ADM2487E are isolated RS‑485/RS‑422 transceivers that provide up to 15 kV ESD protection, selectable 5 V or 3.3 V supply, and 2500 Vrms isolation for one minute. They support data rates of 500 kbps or 16 Mbps and operate over a temperature range of –40 °C to +85 °C.
The devices use Analog Devices’ iCoupler technology, integrating a three‑channel isolator, a three‑state differential driver, and a differential receiver in a 16‑lead wide‑body SOIC package. Features include true fail‑safe receiver inputs, thermal shutdown protection, and high common‑mode transient immunity (>25 kV/µs).
