Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Use short, direct traces for analog signals and avoid crossing digital signals over analog signals.
Optimize the ADC's performance by selecting the correct gain, offset, and sampling rate for your application. Use the device's built-in calibration features and adjust the PGA gain to maximize the signal-to-noise ratio.
Power up the device in the following sequence: AVDD, DVDD, and then the analog input signal. Ensure that the power supplies are stable and within the recommended voltage range before applying the analog input signal.
Use shielding, filtering, and grounding techniques to minimize EMI and RFI interference. Ensure that the device is placed in a shielded enclosure and use EMI filters on the analog input signals.
Use a common clock signal to synchronize multiple devices. Ensure that the clock signal is clean and stable, and use a clock buffer to distribute the clock signal to each device.
