ON Semiconductor LM393S Dual Differential Comparator

The LM393S from ON Semiconductor is a versatile dual differential comparator designed to accommodate a wide range of applications in the electronics industry. This high-performance device is engineered to provide reliable and fast performance for systems requiring voltage level detection and signal comparison.

The LM393S features two independent voltage comparators that are capable of operating from a single power supply over a wide range of voltages, or from dual supplies for more flexibility in complex circuits. This makes it an ideal choice for designers looking for a comparator that can be easily integrated into both low-voltage and high-voltage systems.

Each comparator in the LM393S has a separate input and output, providing the ability to configure the device for various applications such as limit comparators, simple analog-to-digital converters, pulse, square-wave, and time delay generators. Its open collector outputs can be connected to other open-collector outputs to achieve wired-AND relationships, adding to the versatility of the device.

Key features of the LM393S include:

• Wide single-supply voltage range: 2.0 V to 36 V, or dual supplies: ±1.0 V to ±18 V.
• Low supply current drain independent of the supply voltage: 0.4 mA typical.
• Low input biasing current: 25 nA typical.
• Low input offset current: ±5 nA typical.
• Input common-mode voltage range includes ground.
• Differential input voltage range equal to the power supply voltage.
• Low output saturation voltage: 250 mV typical at 4 mA.

The LM393S is designed to operate over a wide temperature range, making it suitable for industrial, automotive, and consumer applications where temperature variations are a concern. The robustness of the LM393S is further assured by its ability to handle currents and voltages that exceed the supply limits, without damage or logic error.

With its precision specifications and durable design, the LM393S from ON Semiconductor is a reliable component for any project needing an efficient and accurate voltage comparison solution.
