ADR431BRZ Frequently Asked Questions (FAQs)

  • The recommended input voltage range for the ADR431BRZ is 4.5V to 18V, although it can operate with input voltages as low as 3.5V.
  • To ensure the output voltage of the ADR431BRZ remains stable over temperature, it is recommended to decouple the input pin with a 10uF capacitor and use a low-ESR capacitor (e.g. ceramic or film capacitor) for the output capacitor.
  • The typical output noise of the ADR431BRZ is 100uVpp (peak-to-peak) from 0.1Hz to 10Hz, and 20uVrms (root mean square) from 10Hz to 100kHz.
  • Yes, the ADR431BRZ is suitable for use as a reference voltage for an ADC due to its low noise and high stability. However, the specific requirements of the ADC should be considered, such as the voltage range and noise tolerance.
  • To minimize noise and ensure optimal performance of the ADR431BRZ, it is recommended to follow good PCB layout practices, such as keeping the input and output traces separate, using a solid ground plane, and minimizing the distance between the device and the decoupling capacitors.
