CAUTION: 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.

Notes: (1) Absolute linearity is utilized to determine actual wiper resistance versus expected resistance = (R_H(n)(actual)-R_H(n)(expected)) = ±1
Ml Maximum. n = 1 .. 29 only
(2) Relative linearity is a measure of the error in step size between taps = R_H(n+1)—[R_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 its initial value.
