NOTES:
3. Absolute linearity is utilized to determine actual wiper voltage vs expected voltage = [V_W(n)(actual) - V_{W(n)(expected )}] = ±1 MI Maximum.
4. Relative linearity is a measure of the error in step size between taps = V_{W(n + 1)} - [V_{W(n) + MI}] = +0.2 MI.
5. 1 MI = Minimum Increment = R_TOT/99.
6. Typical values are for T_A = +25°C and nominal supply voltage.
7. This parameter is not 100% tested.

Power-up and Down Requirements
At all times, voltages on the potentiometer pins must be less
than ±V_CC. The recall of the wiper position from non-volatile
memory is not in effect until the V_CC supply reaches its final
value. The V_CC ramp rate specification is always in effect.
