LM321MFX Frequently Asked Questions (FAQ)

  • The maximum power dissipation of the LM321MFX 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 is an op-amp, it can be used as a comparator in certain applications. However, it's not recommended for high-speed or high-frequency comparator applications due to its limited slew rate and bandwidth.

  • To ensure stability, make sure to follow proper compensation techniques, such as adding a capacitor in the feedback loop or using a resistor in series with the feedback capacitor. Additionally, ensure that the gain and phase margins are sufficient to prevent oscillations.

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

  • Yes, the LM321MFX can be used in a single-supply configuration, but it's essential to ensure that the input common-mode voltage is within the specified range to maintain proper operation.
