NOTES:
12. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested.
13. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
14. 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.
15. MI = RTOT/255 or (VH/RH—VL/RL)/255, single potentiometer.
16. Max = all four arrays cascaded together; typical = individual array resolutions.

NOTES:
17. This parameter is periodically sampled and not 100% tested.
18. tPUR and tPUW are the delays required from the time the third (last) power supply (VCC, V+ or V-) is stable until the specific instruction can be
issued. These parameters are periodically sampled and not 100% tested.
19. Sample tested only.
