CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.

θ
JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
4. For
θJC, the “case temp” location is taken at the package top center.

NOTES:
5. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (Vw(n)(actual) - Vw(n)(expected)) = ±1 Ml Maximum.
6. Relative linearity is a measure of the error in step size between taps = RW(n+1) - [Rw(n) + Ml] = ±0.2 Ml.
7. 1 Ml = Minimum Increment = RTOT/31.
8. Typical values are for TA = +25°C and nominal supply voltage.
9. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested.
