The LM2901N/NOPB is a versatile quad differential comparator produced by Texas Instruments, designed for applications requiring multiple voltage comparisons. This integrated circuit is capable of operating over a wide range of voltages, from a single 2V supply up to a dual ±18V supply, making it suitable for a variety of electronic systems.

This comparator features four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Each comparator has been specifically designed to operate with a low supply current, making it ideal for battery-powered devices and other low-power applications. The LM2901N/NOPB is characterized for operation from -40°C to 125°C, ensuring reliable performance in diverse environmental conditions.

One of the key advantages of the LM2901N/NOPB is its open-collector outputs, which allow wired-AND connections and provide the capability to connect the output to different voltage levels, independent of the supply voltage. This feature is particularly useful in mixed-voltage systems and allows for easy interfacing with digital logic components.

The device is provided in an industry-standard 14-pin PDIP (Plastic Dual-In-Line Package), which is RoHS compliant and lead-free (NOPB: No Lead (Pb) Plating). The LM2901N/NOPB can be used in a range of applications including limit comparators, simple analog-to-digital converters, pulse, square-wave, and time delay generators, as well as voltage monitoring and window comparators.

With its robust design and reliable performance, the LM2901N/NOPB from Texas Instruments is an ideal choice for designers looking for a cost-effective solution for their voltage comparison needs. Its versatility and ease of use make it a valuable component in applications ranging from consumer electronics to industrial control systems.
