Overview
The ADM1485ANZ is a high-speed, half-duplex RS422/RS485 transceiver designed by Analog Devices Inc. to facilitate communication in industrial environments. It supports both RS422 and RS485 protocols, making it versatile for various applications. The transceiver operates with a single driver and receiver (1/1 configuration) and is optimized for high-speed data transmission up to 30 Mbps. It features enhanced noise immunity due to a receiver with 70 mV hysteresis and is designed to operate in harsh environments with a temperature range from -40°C to 85°C.
