The choice of a heat sink for a high-power audio amplifier is. However, to improve system. Upon turn-off, the output of the LM is brought to ground be- fore the power supplies such that no transients occur at power-down. Equation 1 exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage.
The LM has a sophisticated thermal protection scheme. The clamping effect is quite the same. The thermal resistance from the die junction to the outside.
The LM is protected from instantaneous peak. This greatly reduces the stress imposed on the IC by. Taking into account supply line fluc- tuations, it is a good idea to pull out 1 mA per mute pin or 2 mA total if both pins are tied together. Please refer to AN for more detailed information. Thus by knowing the total supply voltage and rated output. Using the best heat sink possible within the cost and space constraints of the system will improve the long-term reliability of any power semiconductor device, as discussed in the Determining the Correct Heat Sink Section.
The package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in each LM Typical Audio Amplifier Application Circuit. An incorrect maximum power dissipation calculation may result in inad- equate heat sinking causing thermal shutdown and thus lim- iting the output power.

Numbers in parentheses represent pinout for amplifier B. This greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions.
Since the die temperature is directly dependent upon the. Once the maximum package power dissipation has been. Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can be calcu- lated. The LM is a stereo audio amplifier capable of delivering. Power dissipation within the integrated circuit package is a.

The waveform to the right of the SOA graph exemplifies how the dynamic pro- tection will datasheeet waveform distortion when enabled. SPiKe Protection means that these. Upon system power-up, the under-voltage protection cir. The LM contains over-voltage protection circuitry that. Special Audio Amplifier Application Circuit 5 www. The clamping effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes.
Since the die temperature is directly dependent upon the heat sink used, the heat sink should be chosen such that thermal shutdown will not be reached during normal opera- tion. Special Audio Amplifier Application Circuit. Refer to the graphs of Power Dissipation versus Output Power in the Typical Performance Characteristics section which show the actual full range of power dissipation not just the vatasheet theoretical point that results from Equation 1.
Using the best heat sink possible within the cost and.
SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks. Taking into account supply line fluc. These instabilities can be eliminated through multiple. Refer to the graphs of Power Dissipation versus.

Single Supply Amplifier Application Circuit. The package dissipation is twice the number which re. This calculation is made using Equation 3. Single Supply Application Circuit. SPiKe Protection Circuitry is not enabled. Operating graph in the Typical Performance Characteris. Since convection heat flow power dissipation is analogous to current flow, thermal resistance is analogous to electrical resistance, and tem- perature drops are analogous to voltage drops, the power dissipation out of the LM is equal to the following: Output Power in the Typical Performance Characteristics.
Equation 1 datasheeet the theoretical maximum power dis.
