(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 specify specific performance limits. Electrical Characteristics state DC and AC electrical  
specifications under particular test conditions which specify 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 PDMAX = (TJMAX − TA) / θJA or the given in Absolute Maximum Ratings, whichever is  
lower. For the LM4952 typical application (shown in Figure 2) with VDD = 12V, RL = 4Ω stereo operation the total power dissipation is  
3.65W. θJA = 20°C/W for the DDPAK package mounted to 16in2 heatsink surface area.  
(5) Human body model, 100pF discharged through a 1.5kΩ resistor.  
(6) Machine Model, 220pF–240pF discharged through all pins.

(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

(3) Typicals are measured at 25°C and represent the parametric norm.  
(4) Limits are ensured to AOQL (Average Outgoing Quality Level).  
(5) Datasheet min/max specification limits are ensured by design, test, or statistical analysis.  
(6) Shutdown current is measured in a normal room environment. The Shutdown pin should be driven as close as possible to GND for  
minimum shutdown current.
