AD7928WBRUZ-REEL 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 ADC input pins away from the digital signals and use a ferrite bead or a filter to reduce noise.
  • The AD7928WBRUZ-REEL has an internal calibration circuitry, but it's recommended to perform an external calibration to ensure accuracy. The calibration procedure involves applying a known input voltage and adjusting the offset and gain registers to achieve the desired accuracy.
  • 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 internal biasing and reference circuits are properly initialized.
  • The AD7928WBRUZ-REEL outputs 12-bit digital data, which can be processed using a microcontroller or a digital signal processor. It's recommended to use a digital filter, such as a moving average or a low-pass filter, to reduce noise and improve the signal-to-noise ratio.
  • The AD7928WBRUZ-REEL has a maximum junction temperature of 150°C. To ensure reliable operation, it's recommended to provide adequate heat sinking, use a thermal interface material, and ensure good airflow around the device. Also, consider using a thermally enhanced package or a heat spreader.
