NOTES:
2. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (V_H(n)(actual)-V_H(n)(expected)) = ±1 Ml Maximum.
n = 1.. 29 only
3. Relative linearity is a measure of the error in step size between taps = V_H(n+1)—[V_H(n) + Ml] = ±0.5 Ml, n = 1 .. 29 only.
4. 1 Ml = Minimum Increment = R_TOT/31.
5. Typical values are for T_A = +25°C and nominal supply voltage.
6. This parameter is periodically sampled and not 100% tested
7. This parameter is not 100% tested.
8. When performing multiple write operations, V_CC must not decrease by more than 150mV from it’s initial value.
9. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
