Description
The ADM2682EBRIZ integrates both the transceiver and the isolation components, which simplifies design and reduces board space. Its isolation is achieved using iCoupler® technology, offering up to 5 kV rms isolation. Additionally, the transceiver includes fail-safe features such as thermal shutdown, open-circuit detection, and short-circuit protection, which help prevent damage due to fault conditions.
This transceiver is suitable for applications like industrial automation, motor control, and process control, where secure and efficient data transmission across long distances is essential. The part is available in a small-form-factor package, making it ideal for space-constrained applications.

2. Integrated Power: The device includes an integrated, isolated DC-to-DC converter, simplifying power supply design by providing a regulated output.
3. Data Rate: Supports data rates up to 500 kbps, suitable for a wide range of RS-485 communication protocols.
4. Full Duplex: It features a full-duplex communication capability, enabling simultaneous two-way communication.
5. ESD Protection: Enhanced electrostatic discharge (ESD) protection up to ±15 kV on the bus pins ensures reliability in harsh environments.
6. Fail-Safe Features: Integrated fail-safe receivers ensure a known output state when the bus is idle, open, or shorted.
7. Thermal Shutdown: Over-temperature protection safeguards the device against operation beyond thermal limits.
8. Compact Package: Available in a compact 16-lead, wide-body SOIC package, which is suitable for space-constrained applications.
These features make the ADM2682EBRIZ ideal for use in applications demanding reliable RS-485 communication, such as industrial automation and process control.
Pinout
Key functions and features include:
1. Isolated Communication: Provides signal and power isolation between the RS-485/RS-422 transceiver and the logic interface.
2. Data Rates: Supports data rates up to 500 kbps.
3. Half-Duplex Communication: Enables bidirectional communication over a single pair of twisted cables.
4. Fail-Safe Receiver Inputs: Ensures a known output state when the input is open, shorted, or terminated but not driven.
5. Thermal Shutdown Protection: Prevents overheating by shutting down the device if excessive temperature is detected.
6. High Common-Mode Transient Immunity: Ensures reliable data communication in noisy environments.
Each pin on the ADM2682EBRIZ serves specific roles such as VCC, GND, data input/output, and control signals for managing data transmission and isolation. For detailed electrical characteristics and pin functions, referring to the official datasheet is recommended.
