CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTE:
4. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

NOTES:
5. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
6. 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.
7. MI = RTOT/1023 or (R_H – R_L)/1023, single pot
8. V_CC, V+, V- must reach their final values within 1ms of each other.
9. n = 0, 1, 2, …,1023; m = 0, 1, 2, …, 1022.
