D/A Converter Design Principles

    To properly select D/A conversion chips and related peripheral circuits, you need to understand the performance indicators and pin functions of various integrated circuits, as well as the functions, interfaces and characteristics of the CPU or computer bus connected to the D/A conversion template. It combines software and hardware design.

　　Also note:

　　(1) Safe and reliable: Try to choose components with good performance and adopt photoelectric isolation technology;

　　(2) The unity of performance and economy: A good design should not only achieve the predetermined performance indicators, but also must consider the economic efficiency of the design. When selecting integrated circuit chips, factors such as speed, accuracy, working environment and economy should be considered comprehensively.

　　(3) Universality: From the perspective of universality, the following three aspects should be considered when designing a D/A converter template: compliance with bus standards and the user being able to arbitrarily select the port address and input method.

　　Design of D/A conversion template

　　Design steps:

　　Determine performance indicators;

　　Design circuit schematics;

　　Design and manufacture circuit boards;

　　Soldering and debugging circuit boards.
