LM339APW Frequently Asked Questions (FAQ)
-
The maximum voltage that can be applied to the input pins is the supply voltage (VCC) + 0.3V, which is typically 36V for the LM339APW.
-
To prevent oscillation, ensure that the input signals are clean and free of noise, and that the comparator output is properly terminated. You can also add hysteresis to the comparator by adding a small amount of positive feedback from the output to the non-inverting input.
-
The minimum input voltage required for the comparator to function correctly is typically around 2V, but this can vary depending on the specific application and the desired accuracy.
-
No, the LM339APW is a comparator, not an amplifier. It is designed to compare two input voltages and output a digital signal indicating which input is higher. It is not suitable for amplifying small signals.
-
The pull-up resistor value depends on the specific application and the desired output current. A good starting point is to use a value between 1kΩ and 10kΩ, and adjust as needed to achieve the desired output current.
