Over recommended operating conditions unless otherwise stated.
Notes:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) Absolute linearity is utilitzed to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
(3) Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a
