ADM3491EARZ Typical application Circuitry

The ADM3491EARZ is a low-power, differential line transceiver, designed by Analog Devices, that operates using a single 3.3 V power supply. It's designed for balanced data transmission and complies with both EIA-485 and EIA-422 standards.

This ADM3491EARZ chip finds extensive application in many scenarios such as industrial control local area networks, telecommunications, building automation, and process control. It allows for robust and reliable communication over long distances and in noisy industrial environments.

In terms of key features, the ADM3491EARZ offers half-duplex communication and supports data rates up to 250 kbps. It provides thermal shutdown protection and contains a differential output that exceeds EIA-485 and EIA-422 requirements.

Considering an application in the realm of building automation, let's outline a specific circuit connection approach:

1. Power Supply: The VCC (Pin 8) of ADM3491EARZ should be connected to the system's 3.3V power supply.

2. Ground Connection: Connect the ground of your system to the GND (Pin 5) of the ADM3491EARZ.

3. Data Transmission & Reception: The data input pin DI (Pin 3) and data output pin RO (Pin 1) of the ADM3491EARZ should be tied to your microcontroller or data processing unit's corresponding data output and input pins, respectively.

4. Enable Pins: The DE (Driver Enable - Pin 2) and RE (Receiver Enable - Pin 4) pins of ADM3491EARZ control the direction of data flow. By setting the DE pin high, the driver gets activated. Conversely, by setting the RE pin low, the receiver gets activated.

5. Differential Bus Connection: The differential bus lines A (Pin 6) and B (Pin 7) of the ADM3491EARZ need to be connected to the corresponding bus of your building automation network.

When designing the circuit, several considerations need to be kept in mind:

1. Supply Decoupling: To reduce high-frequency noise in power supply, a decoupling capacitor (typically 0.1 µF) between the VCC and GND pins of the ADM3491EARZ is recommended.

2. Termination: For high data rate applications or where cable lengths are long, a termination resistor across the differential bus lines (A and B pins) might be needed.

3. Thermal Management: The ADM3491EARZ has thermal shutdown protection, indicating the need for appropriate thermal management in the circuit design.

4. Grounding: Correct grounding is crucial to reduce noise and enable smooth signal transmission. For the ADM3491EARZ, a strong ground connection must be made.

Remember, the specific connection and design can vary based on the details of the system you're integrating the ADM3491EARZ into. Always consider the context and consult the datasheet for the most accurate information.
