The ADM3490EARZ is a 3.3V, low-power, full-duplex RS-485/RS-422 transceiver from Analog Devices. It is designed for balanced data transmission on multipoint bus lines and complies with TIA/EIA RS-485 and RS-422 standards. The device features a single driver and single receiver, supporting data rates up to 12 Mbps.
Key electrical characteristics include a supply voltage range of 3V to 3.6V, a common-mode input voltage range of -7V to +12V, and receiver hysteresis of 50 mV. The transceiver provides robust protection with ±15 kV ESD protection on the RS-485 input/output pins and includes thermal shutdown and short-circuit protection. An open-circuit fail-safe receiver design ensures a known output state when the bus is idle or open.
The ADM3490EARZ is housed in an industry-standard 8-lead narrow SOIC package (8-SOIC) with a gull wing termination style and 1.27 mm lead spacing. It is specified for operation over the industrial temperature range of -40°C to +85°C, making it suitable for demanding environments.
The maximum data rate is 12 Mbps.
The supply voltage range is 3V to 3.6V.
The operating temperature range is -40°C to +85°C.
It comes in an 8-SOIC (0.154", 3.90mm Width) surface-mount package.
The RoHS status is listed as RoHS3 Compliant, but this is unverified.
It provides ±15 kV ESD protection on the RS-485 input/output pins.
Up to 32 nodes can be connected on the bus.
