REF02AZ datasheet by Maxim Integrated Products

REF02AZ Frequently Asked Questions (FAQs)

• What is the typical output impedance of the REF02AZ?
  The typical output impedance of the REF02AZ is around 0.2 ohms, which is relatively low and makes it suitable for driving heavy loads.
• How does the REF02AZ handle input voltage noise?
  The REF02AZ has a built-in noise filter that helps to reject high-frequency input voltage noise, ensuring a stable output voltage. However, it's still recommended to use a bypass capacitor at the input pin to further reduce noise.
• Can I use the REF02AZ in a high-temperature environment?
  The REF02AZ is rated for operation up to 125°C, but its accuracy and stability may degrade at higher temperatures. It's recommended to derate the output voltage and current accordingly, and to consider using a more temperature-stable reference voltage source if high accuracy is required.
• What is the minimum input voltage required for the REF02AZ to operate?
  The minimum input voltage required for the REF02AZ to operate is around 4.5V, but it's recommended to use a minimum input voltage of 5V to ensure stable operation and accurate output voltage.
• Can I use the REF02AZ as a voltage reference for an ADC?
  Yes, the REF02AZ can be used as a voltage reference for an ADC, but it's recommended to consider the noise and temperature coefficient of the REF02AZ when selecting a reference voltage source for high-accuracy ADC applications.
