ADAR7251WBCSZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a star topology for the power supply connections and keep the decoupling capacitors close to the device.
  • To optimize for low power consumption, use the lowest possible clock frequency, disable the internal voltage regulator, and use the power-down mode when not in use. Additionally, use a low-power mode for the ADC and DAC, and minimize the number of conversions per second.
  • The recommended calibration procedure involves a full-scale calibration, followed by a zero-scale calibration. The full-scale calibration involves applying a full-scale input voltage and adjusting the internal gain and offset registers to achieve the desired output code. The zero-scale calibration involves applying a zero-scale input voltage and adjusting the internal offset register to achieve the desired output code.
  • To ensure EMC, use a shielded enclosure, keep the device away from high-frequency sources, and use a common-mode choke or ferrite bead on the power supply lines. Additionally, use a low-pass filter on the analog input lines and ensure that the PCB layout is designed to minimize radiation and susceptibility.
  • The recommended thermal management strategy involves using a heat sink or a thermal pad on the exposed pad of the device, and ensuring good airflow around the device. Additionally, use a thermal interface material (TIM) to fill the gap between the device and the heat sink or thermal pad.
