Digital potentiometer compared with mechanical potentiometer, with a programmable resistance, resistance to change vibration, long service life,Resistance to the pollution of the environment, and other important advantages, therefore, has set up a file in the automatic detection and control, intelligent instruments, consumer electronicsMany important products areas to be successful application. Digital potentiometer cancelled activities a, is a semiconductor integratedCircuit. Its advantage is: adjust high precision; Have very long working life; No mechanical wear; dataBoth; Has the configuration register and data register; The multilevel quantity memory function, especially suitable for audio system;Easy software control; Small volume, easy to assemble.Adopt the most advanced electronic technology potentiometer, SCM control mode, data storage, output resistance and controlled electricity
