ADM2483BRWZ Datasheet

Isolator Interface IC


The ADM2483BRWZ differential bus transceiver is an integrated,galvanically isolated component designed for bidirectional data communication on balanced, multipoint bus transmission lines.It complies with ANSI EIA/TIA-485-A and ISO 8482: 1987(E).Using Analog Devices’ iCoupler technology, the ADM2483 combines a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package.The logic side of the device is powered with either a 5 V or 3 V supply, and the bus side uses a 5 V supply only. ADM2483BRWZ Features • RS-485 transceiver with electrical data isolation• Complies with ANSI TIA/EIA RS-485-A and ISO 8482: 1987(E)• 500 kbps data rate• Slew rate-limited driver outputs• Low power operation: 2.5 mA max• Suitable for 5 V or 3 V operations (VDD1)• High common-mode transient immunity: >25 kV/μs• True fail-safe receiver inputs• Chatter-free power-up/power-down protection 256 nodes on bus• Thermal shutdown protection
