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.
Optimize the ADC's performance by selecting the correct gain setting, adjusting the sampling rate, and using the correct input range. Also, consider using the ADC's built-in features such as the programmable gain amplifier, and the ability to select the input range and sampling rate.
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 ADS8860IDRCR has a latency of 2.5 clock cycles. To handle the latency, ensure that your system can handle the data transfer rate, and consider using a FIFO or a buffer to store the data. Also, consider using the ADC's built-in features such as the data ready signal to synchronize the data transfer.
The ADS8860IDRCR has a built-in calibration feature that can be used to calibrate the ADC. The calibration process involves applying a known input voltage and adjusting the ADC's offset and gain to match the expected output code. The calibration process can be done using the ADC's built-in calibration registers.
