LM321MFX/NOPB Frequently Asked Questions (FAQ)

  • The maximum power dissipation of the LM321MFX/NOPB is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.

  • While the LM321MFX/NOPB is rated for operation up to 125°C, it's essential to consider the device's power dissipation and thermal management to ensure reliable operation in high-temperature environments.

  • To ensure stability, it's crucial to follow proper compensation techniques, such as adding a capacitor in the feedback loop, and to carefully select the gain and bandwidth of the amplifier to avoid oscillations.

  • The input impedance of the LM321MFX/NOPB is typically around 2MΩ, but it can vary depending on the specific application and operating conditions.

  • While the LM321MFX/NOPB can be used as a comparator, it's not the most suitable device for this purpose due to its relatively slow slew rate and limited bandwidth. A dedicated comparator IC would be a better choice.
