LM339MX Frequently Asked Questions (FAQ)

  • The maximum power dissipation of the LM339MX is 500mW. However, it's recommended to derate the power dissipation based on the ambient temperature and package type.

  • Yes, the LM339MX can be used as a comparator with a single supply voltage. However, the input common-mode voltage range is limited to VCC-1.5V to VCC+0.5V, so ensure that the input signal is within this range.

  • The pull-up resistor value depends on the load current and the desired output voltage. A good starting point is to use a 1kΩ to 10kΩ resistor, and then adjust based on the specific application requirements.

  • The LM339MX has a response time of around 1.3μs, which makes it suitable for low-to-medium frequency applications. For high-frequency applications, consider using a faster comparator like the LMH7321 or LMH7221.

  • Yes, the LM339MX can be used as a zero-crossing detector. However, ensure that the input signal is properly biased and the comparator is configured for a low offset voltage to avoid false triggering.
