NOTES:

3. Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a

potentiometer.

4. Relative Linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentiometer. It is

a measure of the error in step size.

5. MI = RTOT/63 or (RH – RL)/63, single pot

6. Max = all four arrays cascaded together, Typical = individual array resolutions.
