ADR434BRZ 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-grounding configuration and avoid routing digital signals near the ADR434BRZ.
  • The ADR434BRZ is factory-calibrated, but it's recommended to calibrate it again after soldering to account for any thermal shifts. Use a precision voltage source and a high-impedance voltmeter to measure the output voltage. Adjust the trim pins (if available) to achieve the desired output voltage.
  • The maximum power dissipation for the ADR434BRZ is 440 mW. Ensure good thermal conductivity by using a thermally conductive PCB material, and provide adequate airflow around the device. Avoid blocking airflow with components or enclosures.
  • While the ADR434BRZ can be used as a voltage regulator, it's not designed for high-current applications. The maximum output current is 10 mA, and the device is intended for precision voltage reference applications, not as a general-purpose voltage regulator.
  • Use a shielded enclosure, and ensure the PCB is designed with EMI/RFI mitigation in mind. Use bypass capacitors and ferrite beads to filter out high-frequency noise. Keep the ADR434BRZ away from sources of EMI/RFI, such as radio transmitters and high-power electrical systems.
