1. Different functions
The main functions of power chip and analog chip are different. Power chips are mainly used to control and drive high-power loads, so the output current and voltage of power chips are relatively large. The analog chip is mainly used to process analog signals, so the input and output current and voltage of the analog chip are relatively small.
2. Different application fields
The application areas of power chips and analog chips are also different. Power chip is mainly used in motor control, frequency converter, LED lights and other high power load control and drive. The analog chip is mainly used in audio signal processing, video signal processing, sensor signal processing and other fields.
3. Different technical difficulties
The technical difficulties of power chips and analog chips are also different. Power chips need to solve the problems of high current and high voltage, so the manufacturing process and design of power chips are difficult. The analog chip needs to solve problems such as noise and temperature drift, so the manufacturing process and design of the analog chip are also relatively difficult.
4. Different design ideas
The design ideas of power chip and analog chip are also different. The design idea of power chip is to convert low level control signal to high level output signal, so the design of power chip focuses on the design of power amplification and protection circuit. The design idea of analog chip is mainly to convert analog signal to digital signal or digital signal to analog signal, so the design of analog chip focuses on the design of analog signal processing circuit.
