AD7849BRZ 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. Also, place the AD7849BRZ close to the analog signal sources and use short, direct traces to minimize noise pickup.
  • The AD7849BRZ 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 and adjusting the offset and gain registers accordingly.
  • 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 any potential damage or incorrect operation.
  • The AD7849BRZ outputs 14-bit or 16-bit data, depending on the mode selected. The output data format can be configured as two's complement or offset binary. The user should ensure that their system is compatible with the selected output data format and word length to prevent data corruption or misinterpretation.
  • The AD7849BRZ has a maximum junction temperature of 150°C. To ensure reliable operation over temperature, the user should ensure good thermal conduction from the device to a heat sink or the PCB, and avoid operating the device near its maximum junction temperature. Additionally, the user should follow proper PCB design and layout practices to minimize thermal gradients and hotspots.
