LMH6643MMX/NOPB Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the LMH6643MMX/NOPB is 1.4W, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 90°C/W.
  • To ensure stability, it's recommended to use a compensation capacitor (Cc) between the output and the inverting input pins. The value of Cc depends on the gain and bandwidth requirements of the application. A good starting point is to use a 10pF to 22pF capacitor.
  • To minimize noise and oscillations, it's recommended to use a star-ground configuration, keep the input and output traces short and away from each other, and use a solid ground plane. Additionally, decouple the power supply pins with 0.1uF to 1uF capacitors.
  • Yes, the LMH6643MMX/NOPB can be used as a unity-gain buffer. However, it's recommended to add a 10Ω to 22Ω resistor in series with the output to improve stability and reduce oscillations.
  • The LMH6643MMX/NOPB has internal ESD protection, but it's still recommended to use external ESD protection devices, such as TVS diodes or ESD arrays, to protect the device from electrostatic discharge.
