ADS8688IDBT Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Also, use short and direct traces for the analog inputs and avoid crossing digital signals over the analog inputs.
  • Use a low-pass filter at the input, add a ferrite bead or a common-mode choke to the power supply, and use a shielded enclosure. Also, consider using a separate analog ground plane and a quiet power supply.
  • The maximum sampling rate of the ADS8688IDBT is 1 MSPS, but it can be limited by the system's clock frequency, analog input bandwidth, and the digital interface used.
  • No, the ADS8688IDBT is designed to operate from a 3.3V power supply. Using a 5V power supply may damage the device or affect its performance.
  • The ADS8688IDBT has an internal calibration circuit that can be enabled through the CAL pin. The device can also be calibrated externally using an external voltage reference and a calibration routine.
