Product Overview: ADM1485ANZ from Analog Devices Inc.

The ADM1485ANZ is a high-speed, differential line transceiver designed by Analog Devices Inc., a leader in the semiconductor industry. This robust component is specifically crafted to facilitate bidirectional data communication on multipoint bus transmission lines. It is a part of the family of transceivers that implement the RS-485 and RS-422 standards, which are widely recognized for their reliability in industrial communication networks.

The ADM1485ANZ operates with a single 5V power supply and is capable of transmitting data rates up to 10 Mbps. Its half-duplex configuration allows for the transmission and reception of data over a pair of twisted-wire conductors, making it an ideal choice for networked control systems, factory automation, and other applications that require high-speed data exchange over long distances with noise immunity.

This device features a differential driver and receiver, which offers extended common-mode range for the bus voltage, thereby enhancing data integrity in electrically noisy environments. The receiver has a fail-safe feature that ensures a known state if the input is open circuit. Furthermore, the ADM1485ANZ includes thermal shutdown and current-limiting features to protect against output driver overload, providing additional reliability and robustness to the system.

The transceiver comes in a narrow 8-pin SOIC package, making it compact and suitable for space-constrained applications. With an operating temperature range of -40°C to +85°C, the ADM1485ANZ is built to perform reliably in a wide range of environmental conditions.

Key features of the ADM1485ANZ include:

• Conforms to RS-485 and RS-422 EIA Standards
• High-Speed Operation: Up to 10 Mbps
• Single 5V Power Supply
