LM339ADR Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the LM339ADR 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 LM339ADR can be used as a comparator with a single supply voltage. However, the input common-mode voltage range is limited to VCC-2V to VCC+0.5V, so ensure that the input voltage is within this range.
  • The pull-up resistor value depends on the load current and the 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 response time of the LM339ADR is typically 1.3μs, which is the time it takes for the output to change state in response to a change in the input voltage.
  • Yes, the LM339ADR can be used as a zero-crossing detector. The device can detect the zero-crossing point of an AC signal by comparing the signal to a reference voltage. The output will switch states when the input signal crosses the reference voltage.
