AD7847BNZ 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 VCC pin and a 0.1uF capacitor for the AVCC pin.
  • The AD7847BNZ has an internal calibration circuit that can be enabled by setting the CAL pin high. The device will then perform a self-calibration sequence. It's recommended to perform a calibration cycle after power-up and after any changes to the reference voltage or input range.
  • The recommended power-up sequence is to first apply the analog power supply (AVCC) followed by the digital power supply (VCC). The digital power supply should be applied after the analog power supply has reached its nominal value. This ensures that the internal analog circuits are powered up before the digital circuits.
  • The BUSY signal is an output that indicates when the AD7847BNZ is busy with a conversion. The BUSY signal should be monitored by the microcontroller and conversions should not be initiated until the BUSY signal is low. This ensures that the AD7847BNZ is not interrupted during a conversion, which could result in incorrect data.
  • The recommended method is to use a low-noise, low-impedance reference voltage source, such as a voltage reference IC or a precision voltage divider. The reference input should be decoupled with a 0.1uF capacitor to reduce noise and ensure a stable reference voltage.
