AD8668ARZ Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the AD8668ARZ 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 2) to prevent oscillations.
  • To minimize noise and EMI, it's recommended to keep the input and output traces short and away from each other, use a solid ground plane, and decouple the power supply with a 10uF capacitor in parallel with a 0.1uF capacitor.
  • While the AD8668ARZ can be used as a comparator, it's not recommended due to its relatively slow slew rate (0.5V/μs) and limited bandwidth (3MHz). A dedicated comparator like the AD8561 or AD9671 would be a better choice.
  • The input bias current of the AD8668ARZ can be calculated using the formula: IB = (VCC - VEE) / (2 * RIN), where RIN is the input resistance and VCC and VEE are the supply voltages.
