The ADM3491ARZ is a low-power, 3.3V full duplex RS-422/RS-485 transceiver from Analog Devices. It features one driver and one receiver, supporting data rates up to 10 Mbps. The device includes a shutdown mode with a typical supply current of 2 nA, and a quiescent current of 1 µA, making it ideal for power-sensitive applications. It can interface with up to 32 transceivers on the bus and operates over a common-mode range of -7 V to +12 V.
The transceiver is specified for the -40°C to +85°C temperature range and is available in a 14-SOIC surface mount package (8.75 mm x 4 mm x 1.5 mm max). Typical applications include low power RS-485/RS-422 networks in telecom, industrial process control, and HVAC systems. The device is interoperable with 5 V logic and features 50 mV receiver hysteresis for noise immunity.
The supply voltage range is 3V to 3.6V, typically 3.3V.
It is available in a 14-SOIC surface mount package (0.154", 3.90mm Width).
The operating temperature range is -40°C to +85°C.
