Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The datasheet provides a recommended layout and routing guide.
To optimize performance in noisy environments, use a low-pass filter on the analog input, use a shielded cable for the analog input, and keep the analog and digital grounds separate. Additionally, use a decoupling capacitor on the power supply pins.
The maximum sampling rate of the ADS8332IRGET is 1 MSPS (million samples per second). However, the actual sampling rate may be limited by the system clock and the conversion time.
The ADS8332IRGET has an internal calibration circuit that can be enabled by setting the CAL bit in the control register. The calibration process takes approximately 100 μs and should be performed after power-up or after a reset.
The power consumption of the ADS8332IRGET depends on the operating mode and the sampling rate. In normal operation, the power consumption is typically around 15 mW. In power-down mode, the power consumption is typically around 10 μW.
