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 Characteristics. Note 2: Human body model, 1.5k Ω in series with 100pF. Machine model, 0Ω in series with 200pF. Note 3: Shorting output to V+ will adversely affect reliability. Note 4: Shorting output to V- will adversely affect reliability. Note 5: The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX)–TA)/θJA. All numbers apply for packages soldered directly into a PC board. Note 6: Typical values represent the most likely parametric norm. Note 7: All limits are guaranteed by testing or statistical analysis. Note 8: RL is connected to mid-supply. The output voltage is GND + 0.2V ≤ VO ≤ V + −0.2V Note 9: Connected as voltage follower with 2VPP step input. Number specified is the slower of the positive and negative slew rates. Note 10: 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 guarantee of parametric performance is indicated in the electrical tables under conditions of internal self heating where TJ > TA. www.national.com 4 |
