ADM2682EBRIZ-RL7 Обзор
An isolated RS-485 transceiver is a component that provides both electrical isolation and differential data communication. It integrates a transceiver with digital isolators and often an isolated power supply, allowing data transmission across a galvanic isolation barrier. This is essential in industrial automation, motor control, and building management systems where different ground potentials can cause damaging ground currents. The ADM2682E belongs to the family of isolated interface ICs, which are part of the broader category of interface and isolation products.
Key features include 5 kV rms isolation voltage, 16 Mbps data rate, 15 kV ESD protection on the bus pins, and an integrated isolated DC-DC converter that eliminates the need for a separate isolated power supply. The device operates from a single 5V supply and provides a regulated 5V isolated output. It is fully specified over the industrial temperature range of -40°C to +85°C and is available in a wide-body SOIC-16 package with >8 mm creepage and clearance.
The ADM2682E uses Analog Devices' iCoupler technology for signal isolation and isoPower technology for isolated power transfer. The isoPower technology uses high-frequency switching elements to transfer power through a transformer, providing a compact and efficient solution. The device features a thermal shutdown and a logic-level fault output, enhancing system reliability.
Typical applications include industrial fieldbus networks, PROFIBUS, Modbus, building automation, and motor control systems. The integrated isolation and power make it ideal for space-constrained designs where board area is at a premium.
When designing with this device, ensure proper PCB layout with adequate creepage and clearance distances, and place decoupling capacitors close to the supply pins. The integrated DC-DC converter requires careful attention to the external transformer and rectifier components as specified in the datasheet.

Заметки по проектированию
Ensure proper PCB layout with adequate creepage and clearance distances (at least 8 mm) between the isolated and non-isolated sides. Place decoupling capacitors (0.1 µF and 10 µF) close to the VCC and VISO pins. Use a solid ground plane on both sides of the isolation barrier.
The integrated DC-DC converter requires an external transformer and rectifier circuit as specified in the datasheet. Use low-leakage inductors and Schottky diodes for efficiency. Ensure the isolated output voltage is regulated to 5V and decoupled with a 10 µF capacitor.
Do not exceed the absolute maximum ratings for supply voltage and bus pin voltages. Ensure proper termination on the RS-485 bus to avoid reflections. The device has thermal shutdown, but adequate thermal relief should be provided on the PCB to prevent overheating.
