REF5040AIDG4 datasheet by Texas Instruments

REF5040AIDG4 Frequently Asked Questions (FAQs)

• What is the typical output voltage tolerance of the REF5040AIDG4?
  The typical output voltage tolerance of the REF5040AIDG4 is ±0.05% (±5 mV) at 25°C.
• How do I ensure the REF5040AIDG4 is stable and accurate?
  To ensure stability and accuracy, decouple the REF5040AIDG4 with a 10-µF capacitor between the OUT and GND pins, and use a low-ESR capacitor (e.g., X5R or X7R) for the bypass capacitor.
• What is the recommended operating temperature range for the REF5040AIDG4?
  The recommended operating temperature range for the REF5040AIDG4 is -40°C to 125°C.
• Can I use the REF5040AIDG4 as a voltage regulator?
  No, the REF5040AIDG4 is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, not to regulate voltage.
• How do I handle the noise sensitivity of the REF5040AIDG4?
  To minimize noise sensitivity, use a low-noise power supply, decouple the REF5040AIDG4 with a 10-µF capacitor, and keep the device away from high-frequency noise sources.
