AD7801BRZ Frequently Asked Questions (FAQs)

  • The AD7801BRZ is a high-precision voltage reference, and its performance can be affected by the PCB layout and component placement. It is recommended to follow a star-grounding scheme, keep the input and output traces short and separate, and avoid running digital signals near the AD7801BRZ.
  • To ensure stability and prevent oscillation, it is recommended to use a 10uF or larger capacitor on the output, keep the output current below 10mA, and avoid using long output traces or cables.
  • The AD7801BRZ has a temperature coefficient of ±1ppm/°C, which means its output voltage can vary by ±1ppm for every 1°C change in temperature. This can affect the overall accuracy of the device.
  • No, the AD7801BRZ is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the current-handling capability of a voltage regulator.
  • It is recommended to use a voltage transient suppressor (TVS) or a zener diode to protect the AD7801BRZ from power-on surges and voltage spikes. Additionally, a 1kΩ to 10kΩ resistor can be used in series with the input to limit the inrush current.
