ADS1258MRTCTEP Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Use short, direct traces for analog signals and avoid crossing digital signals over analog signals. Also, use a common mode filter and a ferrite bead to filter out high-frequency noise.
  • Calibration involves adjusting the gain and offset of the ADC. Use the built-in calibration registers to adjust the gain and offset. You can also use an external calibration signal to adjust the gain and offset. Refer to the datasheet for the calibration procedure.
  • Power up the analog supply (AVDD) first, followed by the digital supply (DVDD). Ensure that the analog supply is stable before applying the digital supply. Also, ensure that the clock signal is stable before applying the digital supply.
  • Use a low-jitter clock source and a clock buffer to drive the CLKIN pin. Ensure that the clock signal is terminated properly to prevent reflections. Use a series resistor and a capacitor to filter out high-frequency noise.
  • Use a low-impedance source to drive the analog input signals. Use a buffer amplifier or an op-amp to drive the analog input signals. Ensure that the analog input signals are within the specified voltage range and that the input impedance is matched to the ADC input impedance.
