LM393N/NOPB 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 prevent oscillation, add a small capacitor (e.g., 10nF) between the output and ground, and/or use a pull-up resistor (e.g., 1kΩ) between the output and VCC.
  • The minimum input voltage difference required for a valid comparison is typically around 1-2mV, but this can vary depending on the specific application and noise conditions.
  • No, the LM393N/NOPB is a comparator, not an amplifier. It is designed to provide a digital output based on the comparison of two input voltages, not to amplify a signal.
  • When the input voltages are very close or equal, the comparator output may oscillate or be unstable. In such cases, consider adding hysteresis (e.g., using positive feedback) or using a Schmitt trigger configuration to improve stability.
