The ADS1294RIZXGR 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 input traces.
The ADS1294RIZXGR has a built-in calibration mechanism, but optimizing gain and offset calibration requires understanding the specific requirements of your application. TI recommends following the calibration procedure outlined in the datasheet and application notes, and adjusting the calibration coefficients based on your specific use case.
To minimize EMI and RFI interference, TI recommends using proper shielding, grounding, and filtering techniques. This includes using a metal shield around the ADS1294RIZXGR, connecting the shield to a solid ground plane, and using EMI filters on the analog input lines.
To ensure data integrity and accuracy, TI recommends using error detection and correction mechanisms, such as CRC checks and data redundancy. Additionally, implementing noise reduction techniques, such as filtering and averaging, can help improve data accuracy in noisy environments.
The ADS1294RIZXGR has specific power sequencing and reset requirements to ensure proper operation. TI recommends following the power-up and reset sequences outlined in the datasheet, including powering up the analog and digital supplies in the correct order and asserting the reset pin at the correct time.
