(1)

Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very

limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical tables under

conditions of internal self-heating where TJ > TA.

(2)

All limits are specified by testing, statistical analysis or design.

(3)

Typical values represent the most likely parametric norm at the time of characterization. Actual typical values may vary over time and

will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production

material.

(4)

Offset voltage temperature drift is determined by dividing the change in VOS at the temperature extremes by the total temperature

change.

(5)

The EMI Rejection Ratio is defined as EMIRR = 20Log ( VRF-PEAK/ΔVOS).
