LM311MX Frequently Asked Questions (FAQ)
-
The maximum voltage that can be applied to the input pins is 30V, but it's recommended to keep it below 15V to ensure reliable operation.
-
To prevent oscillation, add a small capacitor (e.g., 10nF) between the output and the inverting input, and a small resistor (e.g., 1kΩ) between the output and the non-inverting input.
-
The minimum input voltage required is 4.5V, but it's recommended to use a minimum of 5V for reliable operation.
-
No, the LM311MX is a comparator, not an amplifier. It's designed to compare two input voltages and output a digital signal, not to amplify a signal.
-
To reduce power consumption, use a lower supply voltage (e.g., 5V instead of 15V), reduce the input voltage swing, and consider using a lower-power comparator if possible.
