AD8620AR Frequently Asked Questions (FAQs)

  • The maximum power supply voltage for the AD8620AR is ±18V, but it's recommended to operate within ±15V for optimal performance and reliability.
  • To ensure stability, add a 10nF to 22nF capacitor in parallel with a 1kΩ to 2kΩ resistor between the output and the inverting input. This helps to reduce the phase margin and prevent oscillations.
  • Use a star-grounding configuration, with the op-amp's ground pin connected to a central ground point. Keep the input and output traces short and away from each other, and use a ground plane to shield the circuit from EMI.
  • Yes, the AD8620AR can be used as a comparator, but it's essential to ensure that the input common-mode voltage is within the specified range. Also, be aware that the op-amp's output stage is not designed for high-speed switching, so it may not be suitable for high-frequency comparator applications.
  • The AD8620AR has a relatively high input bias current (up to 1.5μA). To minimize the impact, use a high-impedance input source, and consider adding a bias current compensation network. Also, be aware that the input bias current can cause voltage drops across the input resistors, affecting the circuit's overall performance.
