AD7191BRUZ-REEL Typical application Circuitry

AD7191BRUZ-REEL

The AD7191BRUZ-REEL is a low noise, complete analog front end for high precision measurement applications. It contains a 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC) and is well-suited for applications like weigh scales, pressure measurement, and temperature monitoring systems.

Application Scenarios:

The AD7191BRUZ-REEL is ideal for applications requiring high precision and low noise measurements, such as industrial weigh scales, process control systems, and medical instrumentation.

Key Features:

1. Resolution: The ADC offers a 24-bit resolution, ensuring high accuracy in measurements.

2. Input Channels: It supports 4 differential or 8 single-ended input channels, providing flexibility in sensor connections.

3. Data Rate: The device features a programmable data rate up to 4.8 kSPS, suitable for various sampling requirements.

4. Internal Reference: It includes a low noise internal reference, ensuring stable and accurate reference voltage.

5. Interface: The ADC provides a serial interface compatible with SPI for easy integration with microcontrollers or digital processors.

6. Power Supply: The device operates from a single 3 V or 5 V power supply, accommodating different system power requirements.

Circuit Design for a Weigh Scale:

1. Load Cell Connection:

- Differential Inputs: Connect a load cell to the differential inputs AIN1+ and AIN1- of the AD7191BRUZ-REEL. The load cell's positive output should be connected to AIN1+, and the negative output to AIN1-.

2. Reference Voltage:

- Internal Reference Usage: Utilize the internal reference of the AD7191BRUZ-REEL by connecting REF+ to AVDD and REF- to AVSS, ensuring a stable reference for the ADC.

3. Power Supply:

- Voltage Supply Connection: Power the AD7191BRUZ-REEL with a 5 V supply connected to the AVDD pin, with AVSS connected to ground.

4. Digital Communication:

- SPI Setup: Interface the AD7191BRUZ-REEL with a microcontroller using the SPI pins (CS, SCLK, SDI, SDO) for data communication.

5. Filtering:

- Input Filtering: Implement a low-pass filter at the analog inputs (AIN1+ and AIN1-) to attenuate noise and enhance measurement accuracy.

Design Considerations:

- Noise Management: Pay careful attention to grounding and PCB layout to minimize noise coupling into the sensitive analog inputs.

- Thermal Considerations: Ensure the load cell and ADC are placed in a thermally stable environment to reduce errors due to temperature fluctuations.

- Sensor Calibration: Calibrate the weigh scale system to correct any offset or gain errors in the ADC or load cell.

By adhering to these design principles and leveraging the features of the AD7191BRUZ-REEL, a precise and reliable weigh scale system can be developed.
