REF3425IDBVR Frequently Asked Questions (FAQs)

  • It's recommended to place the REF3425IDBVR close to the ADC or DAC, and use a star-ground configuration to minimize noise. A 4-layer PCB with a solid ground plane is recommended. Keep the input and output traces short and away from noise sources.
  • To ensure accurate voltage reference output, use a low-ESR capacitor (e.g., 10uF) between the VOUT pin and GND, and a 1uF capacitor between the VIN pin and GND. Also, ensure the input voltage is within the recommended range (2.7V to 5.5V).
  • The recommended input voltage range for the REF3425IDBVR is 2.7V to 5.5V. Operating outside this range may affect the accuracy and stability of the voltage reference output.
  • To ensure proper operation, power up the REF3425IDBVR after the input voltage has stabilized. When powering down, ensure the input voltage is removed before the output voltage. A soft-start circuit can be used to control the power-up sequence.
  • The thermal impedance of the REF3425IDBVR package (DBVR) is approximately 125°C/W (junction-to-ambient). Proper thermal design and heat sinking are essential to ensure reliable operation.
