Low-Power Dual Voltage Comparator — featuring wide supply range, open-collector output, and fast response for voltage monitoring, overvoltage protection, and industrial signal comparison.
Product Overview
The LM393DR from Texas Instruments is a high-performance dual voltage comparator featuring low power consumption and wide operating voltage.
It includes two independent precision comparators designed to operate from a single or dual power supply, supporting 2V–36V or ±1V–±18V ranges.
With open-collector outputs for flexible logic interfacing, it’s suitable for voltage detection, power supply supervision, and threshold sensing applications.
Packaged in SOIC-8 (DR), LM393DR provides excellent temperature stability and fast switching response for industrial and embedded applications.
