NOTES:
9. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
10. 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.
11. MI = R_TO_T/255 or (V_H/R_H—V_L/R_L)/255, single potentiometer.
12. Max = all four arrays cascaded together; typical = individual array resolutions.

NOTES:
13. This parameter is periodically sampled and not 100% tested.
14. t_PUR and t_PUW are the delays required from the time the third (last) power supply (V_CC, V+ or V-) is stable until the specific instruction can be
issued. These parameters are periodically sampled and not 100% tested.
15. Sample tested only.
