It expresses the external circuit structure and component parameters of each pin of the integrated circuit, thereby indicating the complete working condition of an integrated circuit.

In some integrated circuit application circuits, the internal circuit block diagram of the integrated circuit is drawn. At this time, it is quite convenient to analyze the integrated circuit application circuit, but there are not many such representation methods.

There are two types of integrated circuit application circuits: the typical application circuit and the practical circuit. The former can be found in the integrated circuit manual and the latter appears in the practical circuit. The two application circuits are not much different. According to this feature, there is no practical application. The circuit diagram can be used as a reference for the typical application circuit diagram, which is often used in repairs.

In general, the integrated circuit application circuit expresses a complete unit circuit, or a circuit system, but in some cases a complete circuit system requires two or more integrated circuits.

Most of the application circuits do not draw the internal circuit block diagram, which is not conducive to recognizing the picture, especially for beginners when performing circuit work analysis.

It is more difficult to analyze the application circuit of the integrated circuit than to analyze the circuit of the discrete component. This is the origin of not knowing the internal circuit of the integrated circuit. In fact, it is better to read the picture and repair it. The integrated circuit is more than the circuit of the discrete component. Convenience.

For the application circuit of the integrated circuit, it is more convenient to understand the picture when the general circuit of the integrated circuit and the role of each pin are understood in detail. This is because integrated circuits of the same type have regularity, and after mastering their commonalities, many integrated circuit application circuits of different models with the same function can be easily analyzed.
