Abstract
En el presente documento se detalla el diseño y la simulación de un potenciómetro digital lineal de resolución seis bits junto con el correspondiente diseño del circuito impreso (PCB) para su posterior montaje y fabricación. El potenciómetro digital se ha diseñado utilizando componentes analógicos y dispositivos electrónicos como los optoacopladores y un regulador de tensión. La utilidad del potenciómetro, es obtener una corriente de salida del sistema configurable en 26 valores de corrientes de carga equidistantes entre sí a partir de 26 combinaciones lógicas binarias que dispondremos en la entrada y que pueden ser controladas y manejadas por un microcontrolador. Para la realización de este proyecto se ha utilizado el software matemático MATLAB y el programa de diseño y simulación de circuitos electrónicos OrCAD. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
In this project the design and simulation of a six bits resolution digital potentiometer is presented. In addition, the corresponding design of the printed circuit board (PCB) for assembly and manufacturing is given. The digital potentiometer has been designed using analog components like common resistances and electronics devices like optocouplers or voltage regulators. The application of the potentiometer is to obtain a controlled current in the output which can be set up in 26 values of load current equidistant from 26 binary logical combinations in the input. This input can be controlled and managed by a microcontroller. MATLAB and OrCAD software has been used for calculation and simulation of the electronic circuits.
