AD797BRZ Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the AD797BRZ 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 (pin 6) to prevent oscillations.
  • For optimal performance, use a star-grounding technique, where the analog and digital grounds are separated and connected at a single point. Keep the input and output traces short and away from noise sources, and use a solid ground plane to reduce electromagnetic interference (EMI).
  • Yes, the AD797BRZ is suitable for buffering high-impedance sources due to its high input impedance (10GΩ) and low input bias current (100pA). However, ensure that the input signal is within the common-mode range of the op-amp to maintain stability.
  • To reduce noise and hum, use a low-noise power supply, decouple the power pins with 10uF and 100nF capacitors, and add a 10Ω to 100Ω resistor in series with the input signal to reduce electromagnetic interference (EMI).
