NOTES:
1. 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
2. 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.
3. 1 Ml = Minimum Increment = R_TOT/31.
4. Typical values are for T_A = 25°C and nominal supply voltage.
5. This parameter is periodically sampled and not 100% tested
6. Typical values are for T_A = 25°C and nominal supply voltage.
7. This parameter is not 100% tested.
8. When performing multiple write operations, V_CC must not decrease by more than 150mV from its initial value.
