LM393ADR 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 ensure a stable output, add a small capacitor (e.g., 10nF) between the output pin and ground to filter out high-frequency noise. Additionally, ensure the input signals are clean and free from noise.

  • The minimum input voltage required is 2V, but it's recommended to operate the comparator with a minimum of 4V to ensure proper functionality.

  • No, the LM393ADR is a comparator, not an amplifier. It's designed to compare two input voltages and output a digital signal, not to amplify a signal.

  • The open-drain output requires an external pull-up resistor to VCC to function correctly. The value of the resistor depends on the specific application, but a typical value is 1kΩ to 10kΩ.
