Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Ch aracteristics. Note 2: Human Body Model (HBM) is 1.5 k Ω in series with 100 pF. Note 3: Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited s elf-heating of the device such that TJ =T A. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self-heating where T J > TA. Note 4: All limits are guaranteed by design or statistical analysis. Note 5: Typical values represent the most likely parametric norm. Note 6: The maximum power dissipation is a function of T J(MAX) , θJA and T A. The maximum allowable power dissipation at any ambient temperature is PD =( TJ(MAX) -T A)/θJA. All numbers apply for packages soldered directly into a PC board. LMV1012 Analog Series www.national.com 4
