LM393MX Frequently Asked Questions (FAQ)
-
LM393MX is a military-grade version of the LM393, with a wider operating temperature range (-55°C to 125°C) and stricter quality control. Otherwise, the electrical characteristics and pinout are identical.
-
Yes, LM393MX is a drop-in replacement for LM393, but keep in mind that the military-grade version may have tighter tolerances and more stringent testing, which may affect the overall performance of your design.
-
The recommended operating voltage range for LM393MX is 5V to 30V, but it can operate up to 36V with reduced performance. It's essential to check the datasheet for specific voltage-related characteristics.
-
To ensure the stability of the LM393MX output, make sure to decouple the power supply lines with capacitors, use a stable reference voltage, and avoid noise and oscillations in the input signals.
-
The typical response time of LM393MX is around 1.3 μs, but this can vary depending on the input signal, supply voltage, and output load. Check the datasheet for specific timing characteristics.
