The ADS1294RIZXGT requires careful PCB layout and routing to minimize noise and ensure optimal performance. TI recommends following the layout guidelines in the datasheet, including keeping analog and digital traces separate, using a solid ground plane, and minimizing the length of analog signal traces.
The optimal gain and filter settings for the ADS1294RIZXGT depend on the specific application and signal characteristics. TI recommends using the device's built-in calibration and test modes to determine the optimal settings, and consulting the datasheet and application notes for guidance.
The recommended power-up sequence for the ADS1294RIZXGT is to first apply the analog power supply (AVDD), followed by the digital power supply (DVDD), and finally the clock signal. This ensures that the device powers up correctly and minimizes the risk of latch-up or other issues.
To minimize EMI and RFI with the ADS1294RIZXGT, TI recommends using proper shielding, grounding, and filtering techniques, such as using a metal shield around the device, connecting the device's exposed pad to a solid ground plane, and using EMI filters on the input signals.
The maximum cable length and type recommended for the ADS1294RIZXGT's analog input signals depend on the specific application and signal characteristics. As a general guideline, TI recommends using shielded, twisted-pair cables with a maximum length of 10 feet (3 meters) to minimize noise and signal degradation.
