AD6644ASTZ-65 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a star topology for the power supply connections and keep the signal traces short and direct.
  • Use a high-quality clock source with a low jitter specification. Ensure the clock signal is properly terminated and use a clock buffer if necessary. Keep the clock signal traces short and away from noisy digital signals.
  • Power up the analog supply (AVDD) first, followed by the digital supply (DVDD). Ensure that the clock signal is stable and valid before applying the analog input signal.
  • Use a FIFO or a buffer to handle the output data and ensure that the data is transferred at a rate that does not exceed the maximum data rate of the device. Use a CRC or checksum to detect errors and ensure data integrity.
  • Perform a full-scale calibration after power-up and after any changes to the analog input signal. Use the on-chip calibration registers to adjust the gain and offset of the ADC. Refer to the datasheet for the recommended calibration procedure.
