The ADM485AR from Analog Devices Inc. is a high-speed, differential line transceiver designed to operate using a single 5 V power supply. This robust device is a part of the industry-standard 485 family and is ideal for bidirectional communication on multipoint bus transmission lines.
Built for balanced data transmission, the ADM485AR features a tri-state differential line driver and differential input line receiver. Both the driver and the receiver can handle up to 32 transceivers on the bus. With a 5V supply, the ADM485AR can achieve data rates up to 5 Mbps, making it suitable for high-speed data communication in industrial, networking, and automation applications.
The device is characterized by its low power consumption, typically only 5 mA, and even less in the power-down mode, making it an energy-efficient choice for modern electronic systems. Additionally, it boasts a wide common-mode voltage range, which provides robustness in electrically noisy environments or where ground potentials may differ.
The ADM485AR's thermal shutdown and short-circuit protection ensure reliable operation and longevity of the device. It is available in an 8-lead SOIC package, which is a compact solution for PCB layouts that require space-saving components. The operating temperature range of -40°C to +85°C allows the device to function effectively in a variety of environmental conditions.
