    LM311PSR Frequently Asked Questions (FAQs)

    • The maximum voltage that can be applied to the input pins is ±30V, but it's recommended to keep it within the supply voltage range to ensure proper operation.
    • To prevent oscillation, add a small capacitor (e.g., 10nF) between the output and ground, and a small resistor (e.g., 1kΩ) in series with the output. This will help filter out high-frequency noise and ensure a stable output.
    • The minimum input voltage required is 2V, but it's recommended to keep it above 4V for optimal performance.
    • No, the LM311PSR 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 pull-up resistor value depends on the load current and the desired output voltage. A general rule of thumb is to choose a value between 1kΩ and 10kΩ. For example, if the load current is 1mA, a 2.2kΩ pull-up resistor would be suitable.
