Texas Instruments provides a recommended layout and routing guide in the ADS1296CZXGT datasheet, but it's also important to follow general high-frequency PCB design guidelines, such as keeping analog and digital traces separate, using a solid ground plane, and minimizing signal loop areas.
The optimal gain and filter settings depend on the specific application and signal characteristics. TI provides a gain and filter calculator tool to help with this, but it's also recommended to experiment with different settings and evaluate the performance using the device's built-in diagnostic features.
To minimize EMI and noise, use a shielded enclosure, keep the device away from noise sources, use a low-pass filter on the input signals, and ensure good power supply decoupling. Additionally, use the device's built-in noise reduction features, such as the noise filter and lead-off detection.
To ensure accurate and reliable data acquisition, follow proper PCB design and layout guidelines, use a stable and clean power supply, and ensure proper signal conditioning and filtering. Additionally, use the device's built-in diagnostic features, such as the internal oscillator and voltage reference, to monitor and adjust the device's performance.
The maximum data rate of the ADS1296CZXGT depends on the specific configuration and operating mode. In general, the device can achieve data rates up to 32 kSPS per channel, but this may be limited by the system's overall bandwidth and noise performance.
