*COMMENT

Stresses above those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device.

This is a stress rating only and 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 condi-

tions for extended periods may affect device reliability.

Test Conditions/Notes

RTOTAL ≤ 50KΩ

IW = 1mA, VCC = 5V

IW = 1mA, VCC = 2.7V

Ref: 1kHz

Vw(n)(actual) – Vw(n)(expected)

Vw(n+1) – [Vw(n)+MI]

See circuit #3

Notes:

(1) Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage

= (Vw(n)(actual) – Vw(n)(expected)) = ±1 Ml Maximum.

(2) Relative Linearity is a measure of the error in step size between taps = VW(n+1) – [Vw(n) + Ml] = ±0.2 Ml.

(3) 1 Ml = Minimum Increment = RTOT/31.

(4) Typical values are for TA = 25°C and nominal supply voltage.

(5) This parameter is periodically sampled and not 100% tested.
