    ADM2682EBRIZ Typical application Circuitry Schematics

    ADM2682EBRIZ

    Analog Devices makes a signal and power isolated RS-485 transceiver called the ADM2682EBRIZ. It comes with an integrated transformer driver on-chip to simplify the design and reduce the BOM cost. According to EIA specifications RS-485 and RS-422, the ADM2682E transceiver is made for bidirectional data transfers on multipoint bus transmission lines. Here is a generalized guide for connecting the ADM2682EBRIZ in your circuit:

    1. Power Supply: Connect the VCC1 pin to a 3.3V or 5V supply, and the GND1 pin to the ground plane. VCC2 should be connected to a 5V supply and GND2 to the corresponding ground plane. Please ensure that the isolation barrier requirements are met in your design.

    2. RS-485 Bus Connection: The A and B pins are the differential line interface pins for the RS-485 bus. They are connected to the differential pair of the RS-485 cable.

    3. Driver Inputs: The driver input pins, DI and DE, are connected to the transmitting device's (like a microcontroller) output pins. DI (Driver Input) receives the data to be transmitted to the RS-485 bus and DE (Driver Enable) controls whether the driver is active or in a high-impedance state.

    4. Receiver Outputs: The receiver output pins, RO and /RE, are connected to the receiving device's input pins. RO (Receiver Output) provides the data received from the RS-485 bus and /RE (Receiver Enable) controls whether the receiver is active or disabled.

    5. Bypass Capacitors: It's recommended to connect bypass capacitors between the VCC1 and GND1 pins, and the VCC2 and GND2 pins, to provide power supply filtering.

    6. Isolated DC-DC Converter: The ADM2682EBRIZ has an integrated isolated DC-DC converter. The DC-DC converter requires an external transformer for operation. The primary winding is connected to the VDD1 and SW pins, and the secondary winding is connected to the VDD2 and RTN pins. The output (VOUT2 and GND2) should be decoupled with capacitors.

    7. Termination Resistor: If the transceiver is located at either end of the bus, a termination resistor may be required across the A and B lines to match the impedance of the bus and minimize reflections.

    Please consult the ADM2682E data sheet for the exact value of the bypass capacitors, transformer specifications, and other detailed information for your specific application. Remember that this guide is quite general and may not cover all specifics or edge cases for your particular design or use case. Always design in accordance with the regulations and safety standards applicable to your application.
