Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Use short, direct traces for analog signals, and avoid crossing digital signals over analog signals. Also, use a common mode filter or a ferrite bead to filter out high-frequency noise.
To optimize the ADC's performance, ensure that the input signal is within the specified range, and use the correct gain setting. Also, adjust the sampling rate and clock frequency according to your application's requirements. Additionally, consider using the ADC's built-in features such as the programmable gain amplifier and the digital filter to improve performance.
The recommended power-up sequence is to first apply the analog power supply (AVDD), followed by the digital power supply (DVDD), and then the clock signal. This ensures that the ADC is properly initialized and configured before starting conversions.
The ADS8864IDRCR has built-in error detection mechanisms such as the 'busy' signal and the 'error' signal. Use these signals to detect and handle errors during conversions. Additionally, implement error handling routines in your firmware to handle exceptions such as overflow, underflow, and CRC errors.
The ADS8864IDRCR has a built-in calibration mechanism. Perform a self-calibration by writing the calibration command to the ADC's control register. This will adjust the ADC's offset and gain to ensure optimal performance.
