Power Up and Down Requirements
The are no restrictions on the power-up or power-down conditions of VCC and the voltages applied to the potentiometer pins
provided that VCC is always more positive than or equal to VH, VL, and VW, i.e., VCC VH, VL, VW. The VCC ramp rate spec is
always in effect.
NOTES:
1. Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage = (Vw(n)(actual)–Vw(n)(expected)) = ±1 Ml Maximum.
2. Relative Linearity is a measure of the error in step size between
taps = VW(n+1) – [Vw(n) + Ml] = ±0.2 Ml.
3. 1 Ml = Minimum Increment = RTOT/31.
4. Typical values are for TA = 25°C and nominal supply voltage.
5. This parameter is periodically sampled and not 100% tested.
