LM339DR Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the LM339DR is 640mW, which is calculated based on the maximum junction temperature (Tj) of 150°C and the thermal resistance (RθJA) of 125°C/W.
  • Yes, the LM339DR can be used as a comparator with a single supply voltage. However, the input common-mode voltage range is limited to 2V below the positive supply voltage, 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 general rule of thumb is to choose a resistor value that limits the output current to 10-20mA. For example, if the output voltage is 5V and the load current is 10mA, a 1kΩ pull-up resistor would be suitable.
  • The propagation delay of the LM339DR is approximately 1.3μs, which is the time it takes for the output to respond to a change in the input signal.
  • No, the LM339DR is not designed to be used as a voltage regulator. It is a quad comparator, and its output is not designed to source or sink high currents. If you need a voltage regulator, consider using a dedicated voltage regulator IC.
