LM393AM Frequently Asked Questions (FAQ)
-
The maximum voltage that can be applied to the input pins is the supply voltage (Vcc) + 0.3V. Exceeding this voltage can cause damage to the device.
-
To prevent oscillation, ensure that the input voltage difference is greater than the input offset voltage (typically 2mV) and that the output is properly terminated with a pull-up resistor.
-
The minimum input voltage difference required for a valid comparison is typically 2mV, but this can vary depending on the specific application and noise conditions.
-
No, the LM393AM is a comparator, not an amplifier. It is designed to provide a digital output based on the comparison of two input voltages, 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.
