Notes: 1. Power Rating between the wiper terminal RWX(n) and the end terminals RHX V SS - for ANY tap position n, (x = 0,1,2).
Notes: 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).
Notes: 3. Relative Linearity is a measure of the error in step size between taps = RWx(n+1) - [Rwx(n) + Ml] = ±0.2 Ml (x = 0,1,2)
Notes: 4. 1 Ml = Minimum Increment = RTOT / (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.
