Rotary encoder with digital potentiometer

Posted on Dec 17, 2012

The circuit in Figure 1 represents an attempt to combine the best of both worlds: the simplicity of a rotary interface and the performance of a digital potentiometer.

Signals A and B of the rotary encoder pass through a quadrature decoder (LS7084 from LSI Computer Systems,, which translates the phase difference between A and B of the rotary encoder into a compatible output, and , that the AD5220 can ac
