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 the negative supply rail, and a small resistor (e.g., 1kΩ) in series with the output to the load.
The minimum input voltage required is 1.5V, but it's recommended to operate the comparator with a minimum of 2V to ensure proper operation.
No, the LM311DG4 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, but it's recommended to consult the datasheet and perform calculations based on the specific application.
