NOTES:
1. Power Rating between the wiper terminal RWX(n) and the end terminals RHX or RLX - for ANY tap position n, (x = 0,1,2).
2. Absolute Linearity is utilized to determine actual wiper resistance versus, expected resistance = (Rwx(n)(actual) - Rwx(n)(expected)) = ±1 Ml
Maximum (x = 0,1,2).
3. Relative Linearity is a measure of the error in step size between taps = RWx(n+1) - [Rwx(n) + Ml] = ±1 Ml (x = 0,1,2)
4. 1 Ml = Minimum Increment = RTOT/(Number of taps in DCP - 1).
5. Typical values are for TA = 25°C and nominal supply voltage.
6. This parameter is periodically sampled and not 100% tested.
