1, master chip This kind of chip mainly controls the function of electronic products through program instructions. Among them, the special functions that are widely used are I\/O, EEPROM, MTP, OPT and so on. It is mainly used in small household appliances and various electronic products with relatively simple functions.
2, the operational amplifier chip is referred to as the operational amplifier, which plays a role in signal amplification. The op amp is the essence of the analog circuit, and the op amp is a chip with a very high magnification. The operational amplifier model is: a positive input, a inverting input, and an output. Using the operation amplifier can realize the signal addition, subtraction, multiplication, differential and other mathematical operations.
The chip is also called integrated circuit, with various functions, responsible for power supply voltage output control, responsible for audio and video processing, and responsible for complex computing processing, the more functional the chip foot is more powerful. If you can give a picture of the circuit board, in indicating the location of the chip, it is generally easy to see the specific role of the chip in the circuit.
