Linear integrated circuits are widely used in analog circuits due to their simplicity, versatility, low cost and high reliability. In many applications, their performance is determined by their working principle. Comparators are no exception. This article will look at two linear comparator ICs -- the LM2901N/SL65262 -- and examine their application field and working principles.

The LM2901N/SL65262 is a dual comparator that can be used in a variety of applications, such as voltage-controlled oscillators, active filters, analog-to-digital converters, active RC filters, and video signal synchronization circuits. The major features of the LM2901N/SL65262 include low power consumption, wide operating power supply range, high speed operation, open-collector output, low supply current, and reducing time delay. It also boasts a high input impedance, low propagation delay, and accurate voltage threshold detection.

In terms of the working principle, the comparator IC is an amplifier with two differential inputs and one output. The two inputs are called the positive and the negative input, with the positive input applied a higher potential than that of the negative input. The output of the comparator gives a logic high output if the positive input voltage is higher than the negative input voltage. Conversely, the output of the comparator will be logic low if the negative input voltage is higher than the positive input voltage. This phenomenon is known as hysteresis, which is beneficial in eliminating false logic outputs due to small differences in the input voltages.

In addition, the LM2901N/SL65262 also features fault protection which prevents damage from input connected beyond the power supply range. The protection circuit monitors the difference between the positive and negative input to detect if the difference exceeds the predetermined threshold, and it also trips the supply current to avoid further harm. This helps to protect the IC and maintain a stable working environment.

Overall, the LM2901N/SL65262 is a simple and efficient dual comparator IC that can be used in a range of linear applications. Its major features include low power consumption, wide operating power supply range, high speed operation, open-collector output, low supply current, and reducing time delay. Additionally, its fault protection mechanism helps to protect the IC and maintain a stable working environment. This versatile, easy-to-use IC makes excellent choice for applications requiring precise comparison between two input voltages.
