AD797ARZ Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the AD797ARZ is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.
  • To ensure stability in a unity-gain configuration, it's recommended to add a 10nF to 22nF capacitor in parallel with a 1kΩ to 2kΩ resistor between the output and the inverting input. This helps to compensate for the op-amp's internal capacitance and ensures stability.
  • For optimal performance, it's recommended to use a star-grounding technique, where the grounds of the power supplies, analog circuits, and digital circuits are connected at a single point. Additionally, keep the input and output traces short and away from noise sources, and use a solid ground plane to minimize electromagnetic interference (EMI).
  • Yes, the AD797ARZ can be used as a buffer amplifier for high-impedance sources. Its high input impedance (10GΩ) and low input bias current (10pA) make it suitable for buffering high-impedance sources without loading them.
  • To minimize EMI, use shielded cables, keep the op-amp and surrounding components away from noise sources, and use a solid ground plane. Additionally, consider using EMI filters or common-mode chokes to reduce electromagnetic radiation.
