Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the device close to the analog signal sources to minimize noise. Additionally, it's recommended to keep the analog and digital grounds separate and connect them at a single point.
To optimize performance in noisy environments, use a low-pass filter on the analog input, keep the analog signal paths short, and use a shielded cable to connect the sensor to the ADS1241E/1KG4. Additionally, consider using a common-mode filter or a differential amplifier to reject common-mode noise.
The maximum sampling rate of the ADS1241E/1KG4 is 2 kSPS, but this can be limited by the settling time of the analog input, the clock frequency, and the system noise. In practice, a sampling rate of 1 kSPS to 1.5 kSPS is more typical.
The ADS1241E/1KG4 has an internal calibration mechanism that can be initiated through the CAL pin. The device can also be calibrated using an external calibration signal. It's recommended to perform a full-scale calibration and a zero-scale calibration to ensure accurate measurements.
The power consumption of the ADS1241E/1KG4 depends on the operating mode and the clock frequency. In normal operation, the device consumes around 15 mW, but this can be reduced to around 5 mW in low-power mode.
