These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) All voltages are measured with respect to the GND pin, unless otherwise specified.  
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for  
which the device is functional, but do not ensure specific performance limits. Electrical Characteristics VDD = 12V state DC and AC  
electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within  
the Operating Ratings. Specifications are not specified for parameters where no limit is given, however, the typical value is a good  
indication of device performance.  
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and  
specifications.  
(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 is P DMAX = (TJMAX − TA) / θJA or the given in Absolute Maximum Ratings, whichever is  
lower. For the LM4950 typical application (shown in Figure 1) with VDD = 12V, RL = 4Ω stereo operation the total power dissipation is  
3.65W. θJA = 20°C/W for both DDPAK and TO220 packages mounted to 16in2 heatsink surface area.  
(5) Human body model, 100pF discharged through a 1.5 kΩ resistor.  
(6) Machine Model, 220pF–240pF discharged through all pins.
