3 / 11 page Electrical Characteristics (Continued) See Test Circuit ( Figure 2); T A = 25˚C; VCC = 12V. Symbol Parameter Conditions Typical (Note 6) Limit (Note 7) Units V ODC Output DC Bias Pins 9, 14 and 16; All Control Inputs at 2.2V 4.0 V DC I O Output Current Pins 9, 14 and 16 5.0 mA Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Note 2: Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may de- grade when the device is not operated under the listed test conditions. Note 3: All voltages are measured wIth respect to GND, unless otherwise specified. Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax, θJA and the ambient temperature, TA. The maximum allowable power dissipation at any temperature is PD = (TJmax −TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For this device, TJmax = 150˚C. The typical thermal resistance (θJA) of these parts when board mounted follow: LM1295N 70˚C/W. Note 5: Human body model, 100 pF capacitor discharged through a 1.5 k Ω resistor. Note 6: Typicals are at TA = TJ = 25˚C and represent most likely parametric norm. Note 7: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level). Note 8: The deviation from a straight line drawn through measured points at 5% and 95% of the ramp is used to calculate distortion. Distortion = 100 (deviation, volts)/(95% value − 5% value, volts). Deviations are measured at 1⁄3 and 2⁄3 of the ramp time period. Note 9: The deviation from a theoretical parabola drawn through the apex of the actual parabola is used to calculate distortion. Distortion = 100 (deviation, volts)/(theoretical parabola, volts) at measuring point. Nine points are measured. Note 10: The amplitude stability versus temperature is typically 1% or less at 100 Hz when a standard 10k 5% 1⁄4W carbon film resistor is connected between pins 21 and 22 and located close to the package. The negative temperature coefficient of the resistor corrects for the negative temperature coefficient of the LM1295. The typical amplitude stability of the LM1295 by itself is 2%. www.national.com 3 |
