LM139J/883 Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the input pins is the supply voltage (Vcc) + 0.3V. Exceeding this voltage can cause damage to the device.
  • To prevent oscillation, ensure that the output is properly terminated with a pull-up or pull-down resistor, and that the input signals are properly filtered to remove noise and glitches.
  • The minimum input voltage differential required for a valid comparison is typically around 1-2 mV, but this can vary depending on the specific application and noise conditions.
  • No, the LM139J/883 is a comparator, not an amplifier. It is designed to provide a digital output based on the comparison of two input signals, not to amplify a signal.
  • When the input signals are very close in voltage, the comparator may oscillate or produce an unstable output. In this case, consider adding hysteresis to the comparator by adding positive feedback or using a Schmitt trigger configuration.
