AD7873ARQZ Frequently Asked Questions (FAQs)

  • The AD7873ARQZ requires careful layout and placement to minimize noise and ensure accurate conversions. A recommended layout is to place the AD7873ARQZ close to the analog signal sources, use a ground plane, and keep the analog and digital signals separate. Additionally, decoupling capacitors should be placed close to the device.
  • To optimize the AD7873ARQZ for low power consumption, use the lowest possible clock frequency, disable the internal reference, and use the power-down mode when not converting. Additionally, consider using a lower voltage supply and reducing the analog input range.
  • The AD7873ARQZ requires a two-point calibration procedure to ensure accurate conversions. The recommended procedure involves applying a known voltage to the analog input and adjusting the offset and gain registers to achieve the desired accuracy.
  • To handle EMI with the AD7873ARQZ, use shielding, filtering, and grounding techniques. Ensure that the device is placed in a shielded enclosure, use EMI filters on the analog inputs, and connect the analog ground to the digital ground.
  • The maximum conversion rate of the AD7873ARQZ is 250 kSPS (kilosamples per second) for 12-bit mode and 125 kSPS for 14-bit mode.
