COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; the functional operation of
the device (at these or any other conditions above
those listed in the operational sections of this
specification) is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect device reliability.
POTENTIOMETER CHARACTERISTICS
(Over recommended operating conditions unless otherwise stated.)
Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (V
H(n)
(actual) - V
H(n)
(expected)) =
±1 Ml Maximum. n = 1 .. 29 only.
(2) Relative linearity is a measure of the error in step size between taps = V
H(n+1)
- [V
H(n)
+ Ml] = ±0.5 Ml, n = 1 .. 29 only.
(3) 1 Ml = Minimum Increment = R
TOT
/31.
(4) Typical values are for T
A
= 25°C and nominal supply voltage.
(5) This parameter only applies to a single potentiometer.
(6) Typical parameter is guaranteed by characterization.
(7) When performing multiple write operations, V
CC
must not decrease by more than 150mV from it’s initial value.
