AD7621ASTZ Frequently Asked Questions (FAQs)

  • A good layout and routing practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the analog and digital signals separate. Also, keep the input and output traces short and away from noise sources.
  • The AD7621ASTZ has an internal calibration circuit that can be enabled by setting the CAL pin high. Additionally, the device can be calibrated using an external calibration signal applied to the CALIN pin.
  • The recommended power-up sequence is to apply the analog supply voltage (AVDD) first, followed by the digital supply voltage (DVDD), and then the clock signal. This ensures that the internal biasing and reference circuits are properly initialized.
  • The AD7621ASTZ outputs 16-bit or 18-bit data, depending on the mode selected. The output data format can be configured as two's complement or offset binary. The word length can be selected as 16-bit or 18-bit using the MODE pin.
  • The AD7621ASTZ has a maximum junction temperature of 150°C. To prevent overheating, ensure good airflow around the device, use a heat sink if necessary, and avoid blocking the thermal pad on the package.
