AD7849CRZ 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 signal traces separate and away from each other. Additionally, use a low-ESR capacitor for the VDD pin and a 0.1uF capacitor for the AVDD pin.
  • The AD7849CRZ has an internal calibration circuit that can be enabled by setting the CAL pin high. The device will then perform a self-calibration sequence. Additionally, the user can perform an external calibration by applying a known voltage to the input pins and reading the corresponding digital output code.
  • The recommended power-up sequence is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD), and then the clock signal. This ensures that the analog circuitry is powered up before the digital circuitry, preventing latch-up or other damage.
  • The AD7849CRZ outputs data in a 16-bit twos-complement format. The user should ensure that the digital output data is properly synchronized with the clock signal and that the data is read correctly to avoid errors. Additionally, the user should handle the output data as signed integers to ensure accurate conversions.
  • The maximum sampling rate of the AD7849CRZ is 200 kSPS. The sampling rate affects the conversion accuracy, as higher sampling rates can introduce noise and reduce the accuracy of the conversions. The user should ensure that the sampling rate is within the recommended range and that the input signal is properly filtered to minimize noise and aliasing.
