ADM2483BRWZ|Isolated RS-485 transceiver
1. Basic Information
The ADM2483BRWZ is a 2.5kV isolated, half-duplex RS-485/RS-422 transceiver from Analog Devices. This robust communication IC integrates iCoupler® isolation technology with a high-speed differential bus transceiver, providing galvanic isolation for industrial networks. Operating from a 3.3V or 5V supply, it features ±15kV ESD protection and supports data rates up to 500kbps. The device comes in a compact 16-lead SOIC package with wide-body spacing for enhanced creepage and clearance. Its -40°C to +85°C industrial temperature range makes it suitable for harsh environments.
2. Key Features
The ADM2483BRWZ offers true galvanic isolation (2.5kV RMS for 1 minute) between logic and bus interfaces, eliminating ground loops. Its fail-safe receiver design ensures logic-high output with open or shorted inputs. The transceiver includes thermal shutdown protection and features low EMI emissions for compliance with industrial standards. With only 2.5mA typical supply current, it provides excellent power efficiency. The integrated isolated DC/DC converter eliminates the need for external isolation components, simplifying design while reducing board space.
3. Applications
This isolated transceiver is ideal for industrial automation systems, motor control networks, and process control equipment. It's widely used in RS-485/RS-422 networks, building automation, HVAC systems, and renewable energy installations. The device excels in applications requiring noise immunity and long-distance communication, such as factory floor networks, instrumentation clusters, and power grid monitoring systems. Its isolation capabilities make it particularly valuable in medical equipment and transportation systems where safety is critical.
4. Selection Advantages
Choosing the ADM2483BRWZ provides superior isolation performance in a single-chip solution, reducing component count and improving reliability. Its high ESD protection safeguards against electrostatic discharges, while the wide operating voltage range offers design flexibility. Analog Devices' iCoupler technology delivers best-in-class noise immunity, and the device's low power consumption extends battery life in portable applications. The integrated solution also simplifies UL, CSA, and VDE safety certifications for end products.
