REF35125QDBVR Frequently Asked Questions (FAQs)

  • A good PCB layout for the REF35125QDBVR involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power supply. Additionally, it's recommended to use a 4-layer PCB with a dedicated analog layer to minimize noise.
  • To ensure proper calibration, follow the calibration procedure outlined in the datasheet, which involves shorting the CAL pin to the output pin and then removing the short. This sets the internal voltage reference to the desired output voltage.
  • The recommended input voltage range for the REF35125QDBVR is 4.5V to 18V. The input voltage affects the output voltage in that a higher input voltage can result in a slightly higher output voltage due to the internal voltage regulator's dropout voltage.
  • The REF35125QDBVR has a built-in power-on reset circuit that ensures the output voltage is stable during power-up. During power-down, the device enters a low-power shutdown mode. System designers should ensure that the power-up and power-down sequences are controlled to prevent unwanted voltage transients.
  • The REF35125QDBVR has a maximum junction temperature of 150°C. Thermal considerations are important, as high temperatures can affect the device's accuracy and stability. Ensure good thermal design practices, such as providing adequate heat sinking and airflow, to maintain optimal performance.
