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

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