Frequently Asked Questions
What is the maximum input offset voltage of the LM393MX/NOPB?
The LM393MX/NOPB has a maximum input offset voltage of 5000 µV (5 mV) at 25°C, making it suitable for precision voltage comparison applications where minimal offset error is required.
What type of output does the LM393MX/NOPB use, and how should it be connected?
The LM393MX/NOPB features open-collector and open-drain outputs. A pull-up resistor must be connected from the output pin to the supply voltage to obtain a logic-high output level. This configuration allows wired-OR connections and flexible logic-level interfacing.
What are typical applications for the LM393MX/NOPB?
Typical applications include battery voltage monitoring, zero-crossing detectors, window comparators, oscillators, and analog signal level detection in industrial, automotive, and consumer electronics systems.
What package does the LM393MX/NOPB come in and what does the /NOPB suffix mean?
The LM393MX/NOPB is housed in an 8-pin Small Outline (SOIC-8) surface-mount package. The /NOPB suffix indicates the device is lead-free (No Lead, No Pb), compliant with RoHS environmental standards.
