REF5020AID datasheet by Texas Instruments

REF5020AID Frequently Asked Questions (FAQs)

• What is the typical output impedance of the REF5020AID?
  The typical output impedance of the REF5020AID is around 0.5 ohms.
• How do I ensure the REF5020AID is stable and doesn't oscillate?
  To ensure stability, make sure to decouple the input pin with a 10uF capacitor, and use a 10nF capacitor on the output pin to ground. Also, keep the PCB layout clean and avoid long traces.
• What is the recommended input voltage range for the REF5020AID?
  The recommended input voltage range for the REF5020AID is between 4.5V and 18V. Operating outside this range may affect the device's performance and accuracy.
• Can I use the REF5020AID in a high-temperature environment?
  The REF5020AID is rated for operation up to 125°C. However, the device's accuracy and stability may degrade at high temperatures. Consider using a thermally-enhanced package or a different voltage reference if high-temperature operation is required.
• How do I calculate the output voltage tolerance of the REF5020AID?
  The output voltage tolerance of the REF5020AID is typically ±0.5% at 25°C. To calculate the tolerance, multiply the nominal output voltage (2.048V or 4.096V) by the tolerance percentage.
