LMH6646MMX/NOPB Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the LMH6646MMX/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, but a typical value is around 10-22pF.
  • To minimize noise and oscillations, it's recommended to use a star-ground configuration, keep the input and output traces short and symmetrical, and avoid running sensitive traces near the power supply or output pins.
  • Yes, the LMH6646MMX/NOPB can be used as a unity-gain buffer. However, the output impedance will be higher than the specified output impedance due to the internal feedback network. Additionally, the bandwidth will be limited to around 100MHz.
  • The ESD protection diodes in the LMH6646MMX/NOPB can affect the input impedance and common-mode range. To minimize the impact, it's recommended to use a series resistor (around 1kΩ) and a capacitor (around 10nF) in parallel with the input pins to filter out high-frequency noise.
