(2) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a potentiometer. (3) 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. (4) LSB = RTOT / 255 or (RH - RL) / 255, single pot (5) n = 0, 1, 2, ..., 255. D.C. OPERATING CHARACTERISTICS Over recommended operating conditions unless otherwise stated. |
