AD7870KNZ Frequently Asked Questions (FAQs)

  • It's essential to follow a good layout and placement strategy to minimize noise and ensure accurate conversions. Place the AD7870KNZ close to the analog signal sources, use a ground plane, and keep digital and analog traces separate. Refer to the AD7870KNZ evaluation board layout as a reference.
  • To minimize power consumption, use the lowest possible clock frequency, disable the internal reference voltage (if not needed), and use the power-down mode when the converter is not in use. Additionally, consider using a lower supply voltage (e.g., 2.7V instead of 5V) if possible.
  • Use a low-pass filter (e.g., RC filter) to remove high-frequency noise and aliasing. The filter's cutoff frequency should be set to at least 10 times the maximum signal frequency. Additionally, consider using a buffer amplifier to drive the analog input signals.
  • The AD7870KNZ outputs data in a 16-bit, two's complement format. Ensure that your microcontroller or processor can handle this format correctly. You may need to perform byte swapping or sign extension depending on your system's requirements.
  • Perform a full-scale calibration by applying a known input voltage (e.g., 0V and VREF) and storing the resulting output codes. Use these codes to calculate the gain and offset values. You can also use the AD7870KNZ's internal calibration feature, which performs a self-calibration routine.
