Two resistance output modes of universal electronic potentiometer module

Abstract

The invention relates to two resistance output modes of a universal electronic potentiometer module, which are complete output schemes especially fitted for the universal electronic potentiometer module according to the utilization characteristics of the potentiometer, namely adjustable resistor output mode and potentiometer output mode. The two output modes have respective advantages and disadvantages, and can complement each other in practical application. The two output modes can be respectively composed of various electronic switching elements and resistance networks. The invention can effectively implement three structure generation modes of the universal electronic potentiometer module: (1) a discrete component and a small scale integrated circuit, and (2) a single chip microprocessor, such as AT89C2051 and the like, which is used as the core, cooperates with program control; and (3) integration of all integrable elements of on the control circuit.

Problems solved by technology

[0002] Mechanical potentiometers have been used for nearly a hundred years. Mechanical potentiometers have mechanical wear, are afraid of vibration, and are easily damaged by frequent actions. Dial switches and resistor networks can also form potentiometers, but there are mechanical breakpoints. Cannot be used in case of continuous requirement, essentially a digital mechanical potentiometer

[0003] There is a digital potentiometer integrated chip, but it requires a large number of peripheral circuits and secondary design to realize the complete function of the potentiometer. Due to the power limitation of the output resistor network and almost no expansion function, its application has great limitations
