D.C. OPERATING CHARACTERISTICS (Over recommended operating conditions unless otherwise stated.)

Notes: (1) Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as

a potentiometer.

(2) Relative Linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potenti-

ometer. It is a measure of the error in step size.
