ON Semiconductor LM393DR2 - Dual Differential Comparator

The LM393DR2 is a high-performance dual differential comparator manufactured by ON Semiconductor, designed to provide a precise voltage comparison solution. This integrated circuit (IC) is widely used in a variety of electronic applications due to its reliability, versatility, and cost-effectiveness.

Key features of the LM393DR2 include its dual independent comparator circuits, which allow for the comparison of two sets of voltages simultaneously. This is essential for systems that require multi-level detection or control. The device operates over a wide single or dual supply voltage range, which can be from 2.0 V to 36 V when using a single supply, or ±1.0 V to ±18 V when using a dual supply. This flexibility makes it suitable for interfacing with both logic systems and simple power supply designs.

The LM393DR2 boasts a low input bias current, typically 25 nA, which is particularly important for energy-sensitive applications. Additionally, the low input offset voltage and offset current enhance the accuracy of the comparator function, ensuring precise operation. The device also features a low supply current drain, independent of the supply voltage, which is beneficial for battery-powered devices where power conservation is crucial.

With its open collector outputs, the LM393DR2 can be connected to other voltages regardless of the supply voltage, offering excellent flexibility in output interfacing. This makes it possible to use the device in a wide range of applications, including limit comparators, simple analog to digital converters, pulse, square wave and time delay generators, and many other functions that benefit from a comparator.

The LM393DR2 is available in a SOIC-8 package, making it easy to integrate into surface mount technology (SMT) based designs. ON Semiconductor's commitment to quality ensures that this comparator meets the stringent requirements for industrial and commercial applications, providing a reliable solution for voltage comparison tasks.

Whether you're designing consumer electronics, automotive systems, or industrial controls, the LM393DR2 from ON Semiconductor is a solid choice for your voltage comparison needs, combining performance with practicality.
