LM139AJ/PB Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the input pins is the supply voltage (Vcc) + 0.3V, but not exceeding 36V.
  • To ensure stability, add a small capacitor (e.g., 10nF) between the output and the inverting input, and a resistor (e.g., 1kΩ) between the output and the non-inverting input.
  • The strobe input (ST) pin is used to latch the output of the comparator, allowing the output to be synchronized with an external clock signal.
  • No, the LM139AJ/PB is a comparator, not an amplifier. It is designed to compare two input voltages and output a digital signal, not to amplify a signal.
  • The pull-up resistor value depends on the load current and the desired rise time. A general rule of thumb is to choose a value between 1kΩ and 10kΩ.
