Quadrature Encoder to Clock and Direction Signal Converter Using LS7084/LS7184

The quadrature LS7084/LS7184 Module is a CMOS quadrature clock converter. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7084 are converted to strings of a Clock and an Up/down direction control. These outputs can be interfaced directly with standard Up/Down counters for direction and position sensing of the encoder. J1

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
