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. X9241A |
