ADM489AN General Description

The ADM489AN is a popular RS-485/RS-422 transceiver manufactured by Analog Devices. It operates with a supply voltage range of 5V ±5% and has a wide common-mode voltage range from -7V to +12V, making it suitable for various industrial and automotive applications. With its half-duplex communication capability, it allows for bidirectional data transfer over long cable lengths, up to 1200 meters at data rates up to 250 kbps. The device features a fail-safe receiver, ensuring a high level of noise immunity in harsh environments. It also incorporates thermal shutdown protection, guarding against over-temperature conditions. The ADM489AN comes in an industry-standard 8-pin DIP (Dual Inline Package) or SOIC (Small Outline Integrated Circuit) package, making it easy to integrate into existing designs.
