Electronic potentiometer module having complete operating characteristic and function

Abstract

An electronic potentiometer module having a complete operating characteristic and a function is an integrated multifunctional electronic potentiometer module formed by combining circuits for the electronic elements. The module is provided with all the characteristics of a mechanical potentiometer and the strong and abundant expansion properties and functions thereof. The module can be directly used in any place requiring the potentiometer. The performance index of the related product especially the nonvolatile and self-power-supply property can be promoted, so as to use the potentiometer module as a mechanical potentiometer. The self-scaled or digital display, multi-coupling sync output, multiple output modes and output properties, multiple output regulating methods, multiple control circuits and multiple input output interface functions are all fit for the requirement of the development of modern electronic technique on the application of the potentiometer.

Problems solved by technology

[0002] Potentiometers are extremely important and indispensable electronic components in the field of electronic technology. Mechanical potentiometers have been used for nearly a hundred years. In the long development process of human electronic technology, potentiometers have been endowed with many important electronic functional characteristics, resulting in mechanical potentiometers. There are many kinds of devices and have become the only indispensable mechanical and electronic components that are widely used and used in the field of electronic technology (for example, in China alone, more than 5 billion mechanical potentiometers are manufactured every year), and there are mechanical potentiometers in mechanical potentiometers. Many disadvantages such as wear, fear of vibration, frequent movement, easy damage, difficult adjustment, low precision, and monotonous functions have far failed to meet the development needs of modern electronic technology.

[0003] DIP switches and resistor networks can also form potentiometers, but they are bulky, have almost no other functions at all, and there are mechanical breakpoints, which cannot be used in many situations where there is a continuous requirement for resistance changes. They are essentially digital mechanical devices.

[0004] Relatively speaking, the performance of the digital potentiometer integrated chip is much higher than that of the mechanical potentiometer, but there are a series of defects in practical applications, such as: a large number of peripheral circuits and secondary design are required to realize the complete function of the potentiometer, So this device is actually just a part of the potentiometer

In addition, due to the integration of the output resistance network, the function expansion has great limitations, so the device is mainly used for mounting on the circuit board and other circuit interfaces, which increases the design of the digital potentiometer during use. burden, because in most cases, especially in the practical application of potentiometers in the industrial field, it is customary and necessary for digital potentiometers to be as simple and functional as mechanical potentiometers
