AD7714AN-5 Typical application Circuitry

AD7714AN-5

The AD7714AN-5 is a high-precision, low-power, 24-bit analog-to-digital converter (ADC) designed for use in a wide range of measurement and control applications. It features a sigma-delta conversion technique, which provides excellent noise rejection and ensures high accuracy and stability over time and temperature.

Applications:

The AD7714AN-5 is suitable for various applications, including process control, industrial automation, data acquisition systems, and sensor interfaces, particularly where low noise and high accuracy are required.

Key Features:

1. 24-bit resolution: Provides high accuracy and fine resolution for measurement applications.

2. Low power consumption: Ideal for battery-powered and portable devices.

3. Programmable gain: This feature enables the user to modify the gain to suit various input signal ranges.

4. On-chip calibration: Ensures accuracy over time and temperature without the need for external calibration.

5. Multiple input channels: Supports multiple analog input channels for flexible signal acquisition.

Circuit Design Example - Temperature Measurement System:

In this application, the AD7714AN-5 is used to measure temperature using a Pt100 RTD (Resistance Temperature Detector) sensor.

1. Sensor Connection:

- Connect the Pt100 RTD sensor to the analog input channels AIN1(+) and AIN1(-) of the AD7714AN-5. This setup allows for differential measurement, reducing noise and improving accuracy.

2. Reference Voltage:

- Connect a 2.5V precision voltage reference to the REF IN(+) and REF IN(-) pins. This provides a stable reference voltage for the ADC conversion process.

3. Digital Interface:

- Connect the serial data output (DOUT), serial data input (DIN), and serial clock (SCLK) pins of the AD7714AN-5 to the corresponding SPI interface pins of a microcontroller. This allows for digital communication between the ADC and the microcontroller.

4. Power Supply:

- Provide a clean and stable power supply to the AVDD and DVDD pins, ensuring that the ADC operates within its specified power requirements.

5. Configuration:

- Program the control registers of the AD7714AN-5 through the SPI interface to set the desired operating mode, gain, and filtering options.

Design considerations include:

- Noise reduction: To reduce noise coupling into the ADC, use appropriate PCB layout strategies, such as isolating analog and digital grounds.

- Thermal Stability: Ensure that the temperature sensor and the ADC are placed in a thermally stable environment to avoid temperature-induced errors.

- Signal Conditioning: Implement appropriate signal conditioning circuits, such as amplifiers or filters, to prepare the sensor signal for ADC conversion.

In conclusion, the AD7714AN-5 is a versatile and high-performance ADC that can be effectively used in precision measurement applications. By carefully considering the application requirements and following good design practices, a reliable and accurate measurement system can be developed.
