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, but it's also recommended to consult with TI's application notes and layout guidelines for more detailed information.
To optimize the performance of the ADS8528SPMR in noisy environments, it's recommended to use a low-pass filter on the input signals, use a shielded cable for the analog input, and to keep the analog and digital grounds separate. Additionally, using a common-mode filter or a ferrite bead on the power supply lines can help reduce noise.
The maximum sampling rate of the ADS8528SPMR is 250 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, the input signal's bandwidth, and the desired signal-to-noise ratio.
The ADS8528SPMR has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage and then adjusting the internal calibration registers to achieve the desired accuracy. The datasheet provides more detailed information on the calibration process.
The power consumption of the ADS8528SPMR depends on the operating mode, sampling rate, and input voltage. Typically, the power consumption is around 15 mW at 250 kSPS, but it can be as low as 5 mW in low-power mode. The datasheet provides more detailed information on power consumption.
