Power Up and Down Requirements
The are no restrictions on the power-up or power-down conditions of V_CC and the voltages applied to the potentiometer pins
provided that V_CC is always more positive than or equal to V_H, V_L, and V_W, i.e., V_CC ≥ V_H, V_L, V_W. The V_CC ramp rate spec is
always in effect.
NOTES:
1. Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage = (V_w(n)(actual)–V_w(n)(expected)) = ±1 Ml Maximum.
2. Relative Linearity is a measure of the error in step size between
taps = V_W(n+1) – [V_w(n) + Ml] = ±0.2 Ml.
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.
