1. Overview
Integrated circuits, as a core component in the field of electronic technology, are widely used in various electronic devices. There are various classification methods, which can be divided according to application fields and different levels of integration. This article aims to deeply explore the classification system of integrated circuits, especially the classification of its application fields and integration levels, so that readers can more systematically understand the diversity of integrated circuits and their corresponding technical characteristics.
2. Integrated circuits classified by application fields
Integrated circuits can be subdivided into multiple categories according to their application fields, including but not limited to televisions, audio, DVD players, video recorders, computers (microcomputers), electronic keyboards, communications, cameras, remote controls, language processing, and alarms and other application-specific integrated circuits.
Integrated circuits for televisions: This category of integrated circuits covers all aspects of television operation, from line and field scanning to signal processing, to microprocessors (CPUs) and memory integrated circuits. Among them, the color decoding integrated circuit, AV/TV conversion integrated circuit, switching power supply and voltage regulator integrated circuit are of particular concern. These components together ensure that the TV can operate efficiently and stably.
Integrated circuits for audio: The performance of audio equipment depends largely on the quality of its internal integrated circuits. Integrated circuits including AM/FM high and medium frequency circuits, stereo decoding circuits, audio preamplifier circuits, etc., work together to amplify, process and output sound signals, making the sound quality clearer and richer.
Integrated circuits for video disc players: The integrated circuits in the video disc player are mainly responsible for the encoding, decoding, processing and driving of video and audio signals. System control integrated circuits and digital signal processing integrated circuits play a vital role in ensuring the high-performance output of the DVD player.
Integrated circuits for video recorders: The integrated circuits inside the video recorder mainly involve functions such as system control, signal processing and driving. These integrated circuits ensure the stability and efficiency of the recorder during recording and playback.

3. Integrated circuits classified according to their level of integration
From the perspective of integration, integrated circuits can be divided into four levels: small-scale integrated circuits, medium-scale integrated circuits, large-scale integrated circuits and very large-scale integrated circuits.
Small-Scale Integrated Circuits: This level of integrated circuits is relatively less integrated but still plays an important role in many basic electronic devices.
Medium-scale integrated circuit: This type of integrated circuit has increased in integration and can undertake more complex electronic processing tasks.
Large-scale integrated circuits: The emergence of large-scale integrated circuits marks the transition of electronic technology to high integration, which greatly improves the functions of electronic equipment.
Very Large Scale Integrated Circuit: This is the most integrated type of integrated circuit at present. It is widely used in high-end computers, communication equipment and other fields. It is an important symbol of the development of modern electronic technology.
