Analog linear comparators are electronic devices that can be used to select either the greatest or the smallest of two analog inputs. Among these linear comparators, LM139DG4 is a popular one, and today we will discuss its application fields and working principle.
LM139DG4 is an analog linear voltage comparator, featuring different input thresholds, adjustable output thresholds, and open-collector outputs. One of its features is that it can compare two different inputs, with one of the inputs featuring an internally generated reference voltage value. Its inputs can accept arbitrary voltages - both unipolar and bipolar. The two input channels can be used independently or in combination to create a reference voltage from one of its inputs.
As far as its application fields, LM139DG4 can be used in a variety of applications, such as temperature monitoring, light intensity measurement, equation solving, voltage regulation, and more. It is also popularly used in single-board computers, where it ensures that the input voltage stays within the operational range. LM139DG4 is more robust than standard analog comparators, making it ideal for applications that require reliable accuracy.
The working principle of LM139DG4 is fairly straightforward. Two different analog inputs are fed into the comparator. The reference source sets the reference voltage, and the two inputs are then compared against one another. If the input voltage is greater than the reference voltage, then the output will be either “high” or “low”, depending on the original logic. If the input voltage is less than the reference voltage, then the output will be the opposite of the reference voltage.
In addition, the LM139DG4 can also be configured for adjustable thresholds and open-collector outputs. This is done by configuring the circuit and programming the device. Adjustable thresholds allow for more precise control and flexibility when adjusting the output voltage. Open-collector outputs allow other components to be used in the circuit to further customize the functionality of the comparator.
Overall, LM139DG4 is an ideal analog linear voltage comparator for applications that require precise accuracy and reliable results. Its adjustable thresholds and open-collector outputs make it a versatile component that can be used in a variety of applications. From temperature monitoring to equation solving, LM139DG4 is an excellent choice for anyone looking for a reliable and economical linear comparator.
