AD7890BRZ-2 Frequently Asked Questions (FAQs)

  • A multi-layer PCB with a solid ground plane is recommended. Use a star-grounding technique, where all analog and digital grounds are connected to a single point, and keep the analog and digital grounds separate. Also, ensure that the AGND and DGND pins are connected together at the AD7890BRZ-2.
  • The AD7890BRZ-2 has an internal calibration circuit. To calibrate, apply a full-scale input voltage, and then toggle the CAL pin high. The device will then perform a self-calibration. For more accurate calibration, use an external calibration voltage source and follow the calibration procedure outlined in the datasheet.
  • The maximum clock frequency for the AD7890BRZ-2 is 640 kHz. Using a higher clock frequency can result in increased power consumption, reduced accuracy, and potential oscillations. It is recommended to use a clock frequency between 100 kHz to 400 kHz for optimal performance.
  • Use external voltage limiting resistors and diodes to protect the analog input pins from overvoltage conditions. Also, ensure that the input voltage does not exceed the maximum rating of 15 V.
  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the clock signal. Improper power-up sequencing can result in incorrect conversions, increased power consumption, and potential damage to the device.
