Operating Ratings indicate conditions for which the device is in- tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and test conditions, see the Electrical Characteristics. Note 2:Human body model, 1.5kΩ in series with 100pF. Machine model, 200Ω in series with 100pF. Note 3: Output currents in excess of±30mA over long term may adversely affect reliability. Note 4: The maximum power dissipation is a function of TJ(max),θ JA, and TA. The maximum allowable power dissipation at any ambient temperature is PD =( TJ(max) -T A)/θ JA. All numbers apply for packages soldered directly onto a PC board. Note 5:Typical values represent the most likely parametric norm. Note 6: All limits are guaranteed by testing or statistical analysis, unless otherwise noted. Note 8:Guaranteed Vos Drift is based on 280 devices operated for 1000 hrs at 150˚C (equivalent to 30 years 55ºC). Note 9: Guaranteed by design only. Note 10: Settling times shown correspond to the worse case (positive or negative step) and does not include slew time. See the Application Note section for test schematic. Note 11:The limits are set by the accuracy of high speed automatic test equipment. For the typical VOS distribution, see the curve on page 4. Note 12:Precision bench measurement of more than 300 units. More than 65% of units had less than 15nV /˚C VOS drift. www.national.com3
