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 elevated 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 the LM1296 is 81˚C/W.

Note 5: Human Body model, 100 pF capacitor discharged through a 1.5 k

Ω resistor.

Note 6: Adjust V1 until VRDCV = 0V, where VRDCV = V13 −VDC15.

Note 7: Typical specifications are specified at TA = 25˚C and represent most likely parametric norm.

Note 8: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).

Note 9: Amplitude stability versus ambient temperature is defined by |V70 −V25|/V25 x 100%, where V70 and V25 are the output sawtooth peak-to-peak amplitudes

at 70˚C and 25˚C respectively.
