ADR291GT9Z Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a low-ESR capacitor for decoupling and place it close to the device.
  • Use a low-impedance voltage source, and decouple the input with a 10uF capacitor. Ensure the input voltage is within the recommended range (2.7V to 5.5V). Also, use a buffer amplifier if the output current exceeds 5mA.
  • The thermal resistance (θJA) of the ADR291GT9Z package is approximately 30°C/W. This value can be used to estimate the junction temperature of the device.
  • The ADR291GT9Z is rated for operation up to 125°C. However, the accuracy and stability of the voltage reference may degrade at higher temperatures. Consider using a thermally conductive material or a heat sink to maintain a lower junction temperature.
  • Use a low-pass filter or a ferrite bead to reduce high-frequency noise. Keep the device away from high-current or high-frequency circuits. Use a shielded cable or a twisted pair for connections to minimize electromagnetic interference.
