Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The analog input traces should be short and direct, and the digital output traces should be routed away from the analog inputs. Additionally, decoupling capacitors should be placed close to the device.
To minimize high-frequency noise and EMI, use a shielded enclosure, and ensure that the PCB is properly grounded. Use ferrite beads or common-mode chokes to filter out high-frequency noise on the power supply lines. Additionally, use a low-pass filter on the analog input signals to reject high-frequency noise.
The maximum sampling rate of the ADS8328IRSAT is 100 kSPS. However, the actual sampling rate may be limited by the system clock frequency, the conversion time, and the settling time of the analog input signal.
The ADS8328IRSAT has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage and adjusting the internal calibration registers to achieve optimal accuracy. The calibration process should be performed at the operating temperature range of the device.
The power consumption of the ADS8328IRSAT is typically around 15 mW at 3.3 V supply voltage. To reduce power consumption, use the power-down mode when the device is not in use, and reduce the clock frequency to the minimum required for the application. Additionally, use a low-power mode for the analog input buffer to reduce power consumption.
