2. This parameter is tested initially and after a design or process change that affects the parameter.
3. Integral Non-Linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as
a potentiometer.
4. Differential Non-Linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a
potentiometer.
5. LSB = (RHM RLM)/127; where RHM and RLM are the highest and lowest measured values on the wiper terminal.
6. n = 1, 2, ..., 127
7. VDD @ RH; VW measured @ RW with no load.
8. Rw and RL in the range of 0 V and VDD.
