LM393P Frequently Asked Questions (FAQ)

  • 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, add hysteresis to the comparator by connecting a resistor and capacitor between the output and the non-inverting input. This creates a Schmitt trigger configuration.

  • The minimum input voltage required is 1.5V, but the device can operate down to 1.2V with reduced performance. Below 1.2V, the device may not function correctly.

  • No, the LM393P is a comparator, not an amplifier. It is designed to compare two voltages and output a digital signal, not to amplify a signal.

  • To reduce power consumption, use a lower supply voltage (VCC) and reduce the frequency of the input signal. You can also use a voltage regulator to regulate the supply voltage.
