REF194ESZ Frequently Asked Questions (FAQs)

  • The recommended output capacitor value is 10uF to 22uF, but it can be adjusted based on the specific application and noise requirements.
  • To ensure stability and accuracy, make sure to follow proper PCB layout guidelines, decouple the input and output pins, and use a low-ESR output capacitor. Also, ensure the input voltage is within the recommended range and the device is operated within its specified temperature range.
  • The REF194ESZ is specified to operate from -40°C to 125°C, but its accuracy and stability may degrade at higher temperatures. If your application requires high-temperature operation, consider using a voltage reference with a higher temperature rating or implementing additional temperature compensation.
  • To minimize noise and ripple, use a low-ESR output capacitor, decouple the input and output pins, and ensure good PCB layout practices. Additionally, consider adding a noise-reducing capacitor (e.g., 10nF) between the output and ground.
  • Yes, the REF194ESZ is suitable as a reference for ADCs or DACs. Its low noise and high accuracy make it a good choice for precision analog-to-digital or digital-to-analog conversions.
