Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital traces separate. Also, use a low-ESR capacitor for the AVDD pin and a 0.1uF capacitor for the REF pin.
Optimize the ADC's performance by selecting the correct clock frequency, setting the correct gain and offset, and using the correct input range and sampling rate for your application. Also, consider using the ADC's built-in calibration features.
The recommended power-up sequence is to power up the AVDD pin first, followed by the DVDD pin, and then the digital interface (e.g. SPI or I2C). This ensures that the ADC is properly initialized and configured.
The ADS7864YB/250 has a pipelined architecture, which means that there is a latency of 2-3 clock cycles between the input sample and the output data. To handle this, use a FIFO or a buffer to store the output data, and consider using a double-buffering technique to ensure continuous data acquisition.
The ADS7864YB/250 is rated for operation from -40°C to 125°C. Ensure reliable operation by providing adequate heat sinking, using a thermally conductive PCB material, and avoiding thermal gradients. Also, consider using thermal simulation tools to optimize the design.
