Electronic potentiometer system has pushbutton interface - 09/26/02 EDN-Design Ideas:    As systems grow smaller, it becomes increasingly attractive to replace mechanical potentiometers with electronic potentiometers, which are smaller and less expensive silicon equivalents. A common interface for such devices comprises a Chip-Select, Increment and, Up/ line. CS activates the device and, on a rising edge of steps the wiper.....(design idea added 1/05)
