The recommended layout and routing for the ADS1258IPHPREP involves keeping analog and digital signals separate, using a solid ground plane, and minimizing trace lengths and loops. TI provides a layout guide and reference design in the datasheet and application notes.
To optimize performance in noisy environments, use a low-pass filter on the analog input, ensure a clean power supply, and use shielding and grounding techniques to minimize electromagnetic interference (EMI). Additionally, consider using the device's built-in noise reduction features, such as the 50/60 Hz notch filter.
Calibration involves adjusting the device's offset and gain to ensure accurate measurements. TI provides a calibration procedure in the datasheet, which involves applying a known input voltage and adjusting the device's internal registers to achieve the desired accuracy.
The ADS1258IPHPREP is specified to operate from -40°C to 105°C. Ensure that the device is properly heatsinked, and that the PCB is designed to dissipate heat effectively. Monitor the device's temperature using an on-chip temperature sensor or an external temperature sensor.
The ADS1258IPHPREP requires a single 5V power supply. Ensure a clean and stable power supply, and use decoupling capacitors to minimize power supply noise. Additionally, consider using a voltage regulator to regulate the power supply voltage.
