AD7840JNZ 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 signal traces away from the digital signal traces. Additionally, use a low-ESR capacitor for the VREF pin and keep the AVDD and DVDD pins decoupled with 0.1uF capacitors.
  • To ensure proper calibration, follow the calibration procedure outlined in the datasheet, which involves writing a specific code to the CAL register. Additionally, ensure that the VREF pin is properly connected and the internal reference voltage is stable.
  • The recommended power-up sequence is to apply AVDD first, followed by 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 BUSY signal indicates when the AD7840JNZ is busy with a conversion. To handle this signal, use it as an input to your microcontroller or FPGA to synchronize the data transfer and ensure that the conversion is complete before accessing the data.
  • The maximum clock frequency for the AD7840JNZ is 20 MHz. Exceeding this frequency may result in incorrect operation or damage to the device.
