Power Rating between the wiper terminal R
WX(n)
and the end terminals R
HX
or R
LX
- for ANY tap position n, (x=1,2).
Absolute Linearity is utilized to determine actual wiper resistance versus, expected resistance = (R
wx(n)
(actual) –
R
wx(n)
(expected)) = ±1 Ml Maximum (x=1,2).
Relative Linearity is a measure of the error in step size between taps = R
Wx(n+1)
– [R
wx(n)
+ Ml] = ±1 Ml (x=0,1,2)
1 Ml = Minimum Increment = R
TOT
/ (Number of taps in DCP - 1).
Typical values are for T
A
= 25°C and nominal supply voltage.
This parameter is periodically sampled and not 100% tested.
