ADS1120IRVAR Frequently Asked Questions (FAQ)
-
The ADS1120IRVAR requires careful PCB layout and placement to minimize noise and ensure accurate conversions. TI recommends placing the device close to the analog signal sources, using a solid ground plane, and keeping analog and digital traces separate.
-
To optimize the ADS1120IRVAR's performance, consider the input signal's frequency, amplitude, and impedance. Adjust the gain, offset, and sampling rate accordingly. Additionally, use the device's built-in calibration features and consider using an external reference voltage.
-
The ADS1120IRVAR outputs 24-bit data. To handle this data, use a microcontroller or FPGA with a 24-bit or 32-bit data bus. Consider using a SPI or I2C interface to communicate with the ADC. Ensure proper synchronization and data alignment to avoid errors.
-
To ensure accuracy and linearity, calibrate the ADS1120IRVAR regularly, especially during temperature changes. Use the device's built-in calibration features and consider using an external reference voltage. Additionally, ensure proper thermal management and minimize thermal gradients.
-
The ADS1120IRVAR requires a clean, low-noise power supply. Use a high-quality voltage regulator and decoupling capacitors to minimize noise and ripple. Ensure the power supply can provide the required current, and consider using a separate analog and digital power supply.
