Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. Additionally, use short and direct traces for the analog inputs, and avoid running digital signals near the analog inputs.
The gain and offset settings depend on the specific application and sensor used. Consult the datasheet and application notes for guidance on calculating the optimal gain and offset values. You can also use the TI Analog Engineer's Pocket Reference or online calculators to help with the calculations.
The maximum sampling rate of the ADS8317IBDGKR is 250 kSPS. However, the actual achievable sampling rate depends on the system clock frequency, conversion mode, and other factors. Higher sampling rates increase power consumption, so it's essential to balance sampling rate with power consumption requirements.
The ADS8317IBDGKR has an internal 2.5V reference voltage, but you can also use an external reference voltage. If using an external reference, ensure it's within the recommended range (2.5V to 5V) and properly decoupled. Consult the datasheet for specific guidelines on reference voltage selection and configuration.
When selecting an analog input filter, consider the frequency range of your signal, noise levels, and the desired filter response (e.g., low-pass, high-pass, band-pass). The ADS8317IBDGKR has a built-in analog input filter, but you may need to add additional external filtering depending on your specific application requirements.
