ADM2582EBRWZ Isolated RS-485/RS-422 Transceiver
The ADM2582EBRWZ is a fully integrated, 2.5kV signal and power isolated RS-485/RS-422 transceiver from Analog Devices, incorporating ADI's iCoupler® digital isolation and isoPower® DC-to-DC converter technologies. This single-chip solution eliminates the need for external isolated power supplies, simplifying design and reducing component count in high-voltage industrial communication systems. Operating from a single 3.3V or 5V supply, it supports data rates up to 16Mbps and is fully compliant with ANSI/TIA/EIA-485-A and ISO 8482 standards. It features robust ±15kV ESD protection on the bus pins, high common-mode transient immunity (>25kV/µs), and fail-safe receiver inputs for open/short circuit conditions. Housed in a 20-lead wide-body SOIC (SOIC-20W) package, it offers excellent thermal performance and occupies minimal board space.
