The maximum voltage that can be applied to the input pins is the supply voltage (VCC) + 0.3V, but not exceeding 36V.
To ensure a stable output, add a small capacitor (e.g., 10nF) between the output and ground, and/or use a pull-up resistor (e.g., 1kΩ) between the output and VCC.
The minimum input voltage differential required for a valid comparison is typically around 1-2mV, but this can vary depending on the specific application and noise conditions.
No, the LM393DG is a comparator, not an amplifier or buffer. It is designed to provide a digital output based on the comparison of two input voltages, not to amplify or buffer signals.
When the input voltages are very close or equal, the comparator output may oscillate or be unstable. In such cases, consider adding hysteresis (e.g., using positive feedback) or using a Schmitt trigger configuration to improve stability.
