Digital Potentiometer Using Optical Rotary Encoder & LS7184

The primary application of the project is to replace the mechanical potentiometer with optical encoder which is long life, accurate, smooth in operation. The simple project has been designed around LS7184 quadrature clock converter IC from LSI semiconductor, AD5220-10 Digital potentiometer from Analog Devices, and optical encoder from Burns. Quadrature clocks derived from optical encoder, when applied to the A
