AD421BR Typical application Circuitry

AD421BR

Analog Devices created the precise digital-to-analog converter (DAC) known as the AD421BR. Because of its current output architecture, it can be used in industrial control applications where a 4–20 mA current loop is frequently employed.

Key Features:

1. Output Range: Provides a programmable current output, typically 4-20mA.

2. Resolution: 16-bit resolution ensures high accuracy in the output current.

3. Integrated Voltage Regulator: Includes a voltage regulator for stable operation.

4. Loop Fault Detection: Features a loop fault detection capability for system diagnostics.

Application Scenario: Industrial Process Control

In an industrial process control system, the AD421BR can be used to control actuators or transmit sensor data over a 4-20mA current loop. Here's a detailed guide for connecting this DAC in such a system:

1. Power Supply: Connect the VDD pin (Pin 16) to a +24V power supply and the GND pin (Pin 8) to the system ground. The integrated voltage regulator ensures stable operation.

2. Current Output: Connect the IOUT pin (Pin 14) to the input of the actuator or the current loop. The current output range can be set to 4-20mA depending on the application requirements.

3. Digital Input: Connect the AD421BR digital input pins (D0-D15) to a microcontroller or digital system that provides the digital data to be converted to the current output.

4. Loop Fault Detection: The AD421BR FAULT pin (Pin 11) can be monitored by the microcontroller to detect any faults in the current loop, such as open or short circuits.

Circuit Design Considerations:

- Power Supply Decoupling: To maintain stable operation and filter out noise, use decoupling capacitors near the power supply pins.

- Digital Signal Integrity: Ensure that the digital signals provided to the DAC are clean and free from noise to maintain accuracy in the current output.

- Current Loop Protection: Implement protection mechanisms, such as surge protection, in the current loop to safeguard the DAC and other components from electrical transients.

- Thermal Management: Consider heat dissipation in the design, especially if the DAC is operating in a high-temperature industrial environment.

By following these guidelines and paying attention to signal integrity and protection, the AD421BR can be effectively used in industrial process control applications to provide accurate and reliable current output for controlling actuators or transmitting sensor data.
