LM311DG Frequently Asked Questions (FAQ)
-
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 pin, and a small resistor (e.g., 1kΩ) between the output and the input pins.
-
The minimum input voltage required for proper operation is 4.5V, but it's recommended to use a minimum of 5V for optimal performance.
-
No, the LM311DG 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 use a value between 1kΩ and 10kΩ.
