REF3425MDBVTEP 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 voltage regulator close to the REF3425.
  • Use a high-quality output capacitor (e.g., 10uF ceramic) and a low-ESR input capacitor (e.g., 1uF ceramic). Ensure the input voltage is within the recommended range (2.7V to 5.5V). Use a low-dropout linear regulator (LDO) or a switching regulator with a low noise output to power the REF3425.
  • The recommended input voltage range is 2.7V to 5.5V. However, the device can operate with an input voltage as low as 2.5V, but with reduced performance and accuracy.
  • Use a high-quality output capacitor (e.g., 10uF ceramic) and a low-ESR input capacitor (e.g., 1uF ceramic). Add a 10nF to 100nF capacitor in parallel with the output capacitor to filter high-frequency noise. Ensure the PCB layout is optimized for minimal noise coupling.
  • The REF3425 has a thermal derating of 6.4mW/°C above 25°C. Ensure proper thermal management, such as using a heat sink or a thermally conductive PCB material, to maintain a safe operating temperature.
