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 ensure a stable output, make sure to add a small capacitor (e.g., 10nF) between the output pin and ground to filter out any noise or oscillations.
The minimum input voltage difference required for the comparator to switch is typically around 1-2mV, but this can vary depending on the specific application and noise conditions.
No, the LM393ADT is a comparator, not an amplifier. It is designed to compare two input voltages and output a digital signal, not to amplify a signal.
The LM393ADT has an open-drain output, which means it can only sink current. If you need a push-pull output, you can add an external pull-up resistor or use an external transistor to create a push-pull output stage.
