The LM119H/NOPB is a quad, single-ended and general-purpose comparator. It is manufactured in the low-power versions, the LM139H and the LM139H-Q1, and they have a wide power supply rating with a temperature range of -55°C to 125°C. The LM119H/NOPB is a linear-comparator and it is used for comparison and signal conditioning applications. It features low power consumption and accuracy, and it has a wide range of analog input and output signals.

Working Principle

The LM119H/NOPB linear-comparator consists of four operational amplifiers that are connected in parallel, allowing them to work in unison. The four amplifiers act as comparators which compare the difference between two analog signals and then, depending on whether or not the output of one of the comparators is greater or lesser than the other, pumps out a voltage. This voltage is then compared to a reference voltage, and if it is larger, the corresponding output of the comparator is turned on, if it is smaller, the output is turned off.

Application Field

The LM119H/NOPB is suitable for a range of applications, due to its many features. The linear-comparator is used in audio applications such as peak detectors, low-frequency low-noise amplifiers, and active filters. It is also used for control and timing applications such as digital circuits and simple logic circuits, and for power conditioning circuitry. Additionally, it is used in automotive electronics, robotics, and medical equipment.

The LM119H/NOPB linear-comparator is reliable and accurate, making it ideal for a range of applications. It has a wide temperature range and a wide power supply range, and it operates with minimal power consumption. Furthermore, it has a small package size and is robust, making it suitable for use in a variety of applications.
