Each rate sample is recorded as a discrete value within which there may be one of 65,536 scales. This continuous record provides extremely accurate measurements of the waveform in digital format. Digital data is converted into digital bits that are recorded by a laser beam in the form of pits and ground on the surface of a CD or DVD
When music or movies are played, the laser reads the pits and drops to a digital-to-analog converter (DAC), which reconstructs the analog waveform based on a digital blueprint. The waveform is amplified and sent via a speaker, ADC and DAC or encoder decoder, referred to as a codec. The analog chip understands the language of the codec.
hybrid chip
Analog chips are important in many areas, including the automotive industry. Analog chips serve as sensors that can detect increases in motor temperature, report the health of the battery, and provide accurate data on other systems. To further combine the digital and analog worlds, many chips are a hybrid of digital and analog chips. While digital technology gets most of the attention, analog technology is about mixing waveforms and gray scales from the human environment into an ideal electronic format.
The analog chip is an integrated analog circuit, mainly composed of resistors, capacitors, transistors, etc., used to process analog signals in the form of continuous functions.
The analog chip includes the power management chip which is responsible for the transformation, distribution and detection of electric energy. The relationship between analog chips and components is close, and the design needs to consider the structure of component layout and the form of parameter matching.
Integrated circuits can usually be divided into two categories: digital integrated circuits and analog integrated circuits. Among them, the digital integrated circuit accounts for about 85% of the integrated circuit market, and the analog integrated circuit accounts for 15% of the share, the main difference between the two lies in the type of signal processing and industry characteristics.

A digital integrated circuit is an integrated circuit that performs arithmetic and logic operations on discrete digital signals (such as binary codes represented by two logic levels of 0 and 1). Its basic unit is a logic gate circuit. It includes memory (DRAM, Flash, etc.), logic circuits (PLDs, gate arrays, display drivers, etc.), and micro-components (MPU, MCU, DSP).

Analog integrated circuit mainly refers to the analog circuit composed of resistance, capacitor, transistor, etc. integrated together to process continuous functional analog signals (such as sound, light, temperature, etc.) integrated circuit, including general analog circuit (interface, energy management, signal conversion, etc.) and special application analog circuit.
