AD5420AREZ-REEL7 Typical application Circuitry

A 16-bit, loop-powered, 4 mA to 20 mA digital-to-analog converter (DAC), the AD5420AREZ-REEL7. This chip was created specifically to power industrial actuators and sensors in a variety of environments.

Common Uses

- Process Control Systems

- Business Automation

- Systems for Data Acquisition

- Instrumentation

Key Specifications

- Output Range: 4 mA to 20 mA

- 16-bit resolution

- Loop-Powered Operation

- On-Chip Fault Detection

- HART connectivity

- Operating Temperature: −40°C to +85°C

Application Example: Process Control Systems

For this instance, we'll consider a Process Control System where precise control of fluid levels is required.

Components You'll Need:

1. AD5420AREZ-REEL7 (DAC)

2. Microcontroller with SPI or serial interface

3. Power supply (24V DC)

4. Decoupling Capacitors

5. Resistors

6. Loop resistor (250 Ω)

7. PCB

Circuit Details

1. Power Source: Attach a 24V DC power supply to the AVDD pin (Pin 2).

2. Ground Connection: Bind the AGND (Pin 3) and DGND (Pin 8) to the system ground.

3. Data Interface: Interlink the SPI interface pins DIN (Pin 4), SCLK (Pin 5), and CS (Pin 6) to the corresponding SPI pins on your microcontroller.

4. Current Output: The IOUT (Pin 1) pin will provide the 4 mA to 20 mA current output. Connect this to a loop resistor of 250 Ω which is connected to the ground.

5. Fault Output: The FAULT (Pin 9) pin can be connected to an MCU input pin to monitor any on-chip faults.

6. Decoupling: Utilize decoupling capacitors (10 μF and 0.1 μF) between the AVDD and AGND pins.

7. Clear Pin: Optionally, wire the CLEAR (Pin 7) to a GPIO pin on your microcontroller to utilize the clear function.

Design Considerations:

1. Noise Suppression: Using quality capacitors and a low-noise power supply will assist in noise suppression.

2. Timing Aspects: Always ensure that SPI timing is compliant with the AD5420AREZ-REEL7's datasheet.

3. Loop Resistance: For loop-powered systems, make certain that the total loop resistance is within permissible limits to correctly source 4-20 mA.

4. Error Handling: Use the FAULT pin to handle any errors or discrepancies that could arise during operation.

5. Temperature Management: The AD5420AREZ-REEL7 can operate under a broad range of temperatures; however, sufficient thermal management should be considered.

In sum, the AD5420AREZ-REEL7 is a powerful, loop-powered DAC suitable for demanding applications like Process Control Systems. It offers a wide range of features, including fault detection and HART compatibility, which make it a versatile option for modern industrial systems.
