X9110 – Preliminary Information
Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used
as a potentiometer.
(2) 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.
(3) MI = RTOT / 1023 or (R_H – R_L) / 1023, single pot
(4) V_CC, V+, V- must reach their final values within 1 msec of each other.
(5) n = 0, 1, 2, …,1023; m =0, 1, 2, …, 1022.

Notes: (6) This parameter is not 100% tested
(7) t_PUR and t_PUW are the delays required from the time the (last) power supply (Vcc-) is stable until the specific instruction can be
issued. These parameters are not 100% tested.
