With one driver and one receiver on-chip, this part handles point-to-point or multi-drop RS-485 networks up to the standard 32-unit load limit. Analog Devices has not issued a PCN for this MPN, so the date-code and marking consistency across reels should be stable — a key check for gray-market lots. ROHS3 compliant, no exemption conflicts for EU or California markets.","metaTitle":"ADM3490ARZ-REEL7 10 Mbps RS-485/RS-422 Transceiver – Analog","metaDescription":"Analog Devices ADM3490ARZ-REEL7 full-duplex transceiver, 3V–3.6V supply, 10 Mbps data rate, -40°C to 85°C, 8-SOIC.

The 'E' variant typically offers enhanced ESD protection — check the respective datasheets for the exact ESD rating difference. The ADM3491ARZ-REEL7 adds a second receiver (1 driver / 2 receivers) for applications needing an extra monitoring node on the bus."},{"question":"Can ADM3490ARZ-REEL7 be used for RS-485 communication at 10 Mbps?","answer":"Yes, the ADM3490ARZ-REEL7 is specified for RS-485 and RS-422 protocols at a data rate of 10 Mbps. At this speed, the maximum cable length is limited by signal attenuation — typically ~100–200 feet for reliable operation. The 50 mV receiver hysteresis helps reject noise on longer runs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADM3490ARZ-REEL7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADM3490ARZ-REEL7 when reusing this data.
