ADS1231IDR Typical application Circuitry

ADS1231IDR

The ADS1231IDR is a highly integrated, precision 24-bit analog-to-digital converter (ADC) from Texas Instruments, specifically designed for the accurate and direct digitization of low-frequency signals. Part of the ADS123x series, this device is optimized for weighing scales and industrial measurement applications where precision data conversion of sensor inputs is critical. The ADS1231IDR excels in environments requiring minimal external components and straightforward interfacing, thanks to its integrated analog front-end for bridge sensors, onboard low-noise programmable gain amplifier (PGA), and oscillator.

1. Power Supply (AVDD, DVDD Pins): The ADS1231IDR operates with separate analog and digital power supplies to minimize noise interference between the analog and digital circuits. AVDD should be connected to a stable 5V supply, and DVDD may vary from 2.7V to 5.25V, depending on the logic level requirements of the interfacing digital system. Decoupling capacitors should be placed close to both AVDD and DVDD pins to ensure clean power supply lines.

2. Ground Connections (AGND, DGND Pins): The device features separate ground connections for its analog (AGND) and digital (DGND) sections. This separation helps in reducing digital noise from affecting the analog part of the ADC. Both grounds must be connected to the system's ground, but careful PCB layout is necessary to keep the ground paths distinct and minimize noise coupling.

3. Analog Inputs (AINP, AINN Pins): The ADS1231IDR's differential analog inputs, AINP and AINN, are designed for direct connection to bridge sensors or other differential signal sources. These inputs are where the low-frequency signals to be converted are applied. It is crucial to maintain the integrity of these signals with minimal noise intrusion for accurate conversions.

4. Reference Input (REFP, REFN Pins): An external reference voltage can be applied through the REFP and REFN pins to set the ADC's input voltage range. This flexibility allows for precise adjustment of the measurement range to match the sensor output, optimizing the ADC's resolution and accuracy.

5. Serial Data Output (DOUT/DRDY Pin): The converted digital data is output through the DOUT/DRDY pin. This pin also serves as a data ready indicator, signaling when new data is available for reading. The pin should be connected to the serial input of the host microcontroller or digital processor for data retrieval.

6. Serial Clock Input (SCLK Pin): The SCLK pin receives the serial clock signal from an external microcontroller or digital processor. This clock synchronizes the data transfer during serial communication, ensuring accurate and timely data reading.

7. System Control (PDWN, SPEED, Format Pins): The ADS1231IDR includes pins for controlling power-down modes (PDWN), conversion speed (SPEED), and the output data format (Format). These control inputs allow the device to be configured for low-power operation, adjustable sampling rates, and compatibility with different data processing requirements.

Designing a circuit with the ADS1231IDR involves a detailed approach to ensure accurate signal acquisition, minimal noise interference, and efficient data communication. By leveraging the ADS1231IDR's features, developers can create reliable, high-precision measurement systems for applications demanding exacting data conversion, reinforcing Texas Instruments' commitment to advanced sensing and data acquisition solutions.
