APPLICATIONS INFORMATION
Electronic digitally controlled (XDCP) 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.
