Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the ADS1243IPWTG4 close to the analog signal sources to minimize noise. Additionally, it's recommended to use a separate analog ground plane and to keep digital signals away from the analog signals.
To optimize performance in noisy environments, use a low-pass filter on the analog input, use a shielded cable for the analog input, and consider using a common-mode filter. Additionally, ensure that the power supply is clean and well-regulated, and consider using a separate analog power supply.
The maximum sampling rate of the ADS1243IPWTG4 is 2 kSPS, but this can be affected by the clock frequency, the number of channels being converted, and the settling time of the analog input. Consult the datasheet for more information on the sampling rate vs. clock frequency tradeoff.
The ADS1243IPWTG4 has an internal calibration mechanism that can be initiated through the CAL pin. The calibration process involves shorting the analog input to the internal reference voltage, and then adjusting the offset and gain registers to achieve the desired accuracy. Consult the datasheet for more information on the calibration procedure.
The power consumption of the ADS1243IPWTG4 depends on the operating mode, clock frequency, and sampling rate. In normal operation, the power consumption is typically around 15 mW, but this can increase to around 30 mW in high-speed mode. Consult the datasheet for more information on power consumption vs. operating conditions.
