ADR434ARMZ 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 and keep the power traces away from the analog signals.
  • The ADR434ARMZ has an internal calibration circuit that sets the output voltage to 4.096V. No external calibration is required. However, it's essential to follow the recommended PCB layout and decoupling guidelines to ensure the internal calibration circuit operates correctly.
  • The ADR434ARMZ can drive a maximum capacitive load of 10nF. Exceeding this limit may cause oscillations or instability in the output voltage.
  • No, the ADR434ARMZ is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference for analog-to-digital converters, digital-to-analog converters, and other precision circuits. It's not intended to power other components in your design.
  • The ADR434ARMZ has a built-in thermal shutdown feature that disables the output when the junction temperature exceeds 150°C. To handle this, ensure good thermal design practices, such as providing adequate heat sinking and airflow. If the output is disabled due to thermal shutdown, it will automatically recover when the junction temperature drops below 150°C.
