The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of LM393DG, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
LM393DG Frequently Asked Questions (FAQ)
-
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.
