LM393M/NOPB TI Comparators

The LM393 is a dual differential comparator operating from 2 V to 36 V single supply (or ±1 V to ±18 V dual). It features low supply current of 0.8 mA per comparator, 1.3-μs typical response time, and open-collector outputs for wired-AND connections. Input common-mode range includes ground, and the device provides 100 dB typical voltage gain. The LM393 includes internal hysteresis for noise immunity. Packaged in an 8-pin SOIC, this comparator is standard for general-purpose threshold detection in industrial and consumer applications. Applications include window detectors, zero-crossing detectors, battery voltage monitors, oscillator circuits, analog-to-digital converter front-ends, and power supply monitoring in industrial controls, automotive systems, and consumer electronics.
