APPLICATIONS INFORMATION
Electronic potentiometers provide three powerful application advantages: (1) the variability and reliability of a solid-
state potentiometer, (2) the flexibility of computer-based digital controls, and (3) the retentivity of nonvolatile
memory used for the storage of multiple potentiometer settings or data.
