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.
RECOMMENDED OPERATING CONDITIONS
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 is periodically sampled and not 100% tested
(6) This parameter is not 100% tested.
(7) When performing multiple write operations, V
CC
must not decrease by more than 150mV from it’s initial value.
