Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Also, use short and direct traces for the analog inputs and outputs, and avoid crossing digital and analog signals.
To minimize noise, use a low-noise power supply, decouple the power pins with capacitors, and use a quiet analog ground plane. Also, keep the analog input signals away from digital signals and use shielding if necessary.
The ADS8568SRGCT can achieve a maximum sampling rate of 250 kSPS, but this may vary depending on the specific application and system design.
The ADS8568SRGCT has an internal calibration circuit that can be enabled through the CAL pin. The calibration process involves shorting the CAL pin to the analog input, and then releasing it to allow the internal calibration circuit to adjust the offset and gain.
The power consumption of the ADS8568SRGCT varies depending on the operating mode and sampling rate. In normal operation, the power consumption is typically around 35 mW, but this can increase to around 50 mW in high-speed mode.
