Notes:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(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
potentiometer.
(4) LSB = (RHM - RLM)/127; where RHM and RLM are the highest and lowest measured values on the wiper terminal.
(5) n = 1, 2, ..., 127.
(6) V+ @ RH; 0V @ RL; VW measured @ RW, with no load.
(7) Contact factory for availability on this version of the CAT5133.
