POTENTIOMETER CHARACTERISTICS
Notes: 1. Power Rating between the wiper terminal R
WX(n)
and the end terminals R
HX
or R
LX
- for ANY tap position n, (x = 0,1,2).
Notes: 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 = 0,1,2).
Notes: 3. 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)
Notes: 4. 1 Ml = Minimum Increment = R
TOT
/ (Number of taps in DCP - 1).
Notes: 5. Typical values are for T
A
= 25°C and nominal supply voltage.
Notes: 6. This parameter is periodically sampled and not 100% tested.
