Equation 1 exemplifies the theoretical maximum power dis. Refer to the graphs of Power Dissipation versus.
Special Audio Amplifier Application Circuit. Output Power in the Typical Performance Characteristics. Equation 1 exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage.
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.
This greatly reduces the stress imposed on the IC by. This greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions. It starts operating again when the die temperature. SPiKe Protection Circuitry is not enabled.

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 ratasheet together. Thus by knowing the total supply voltage and rated output. Using the best heat sink possible within dataxheet 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.
Using the best heat sink possible within the cost and space constraints of the system datasgeet 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 The choice of a heat sink for a high-power audio amplifier is. LM should have its supply leads bypassed with.
Since the die temperature is directly dependent upon the.
The waveform to the right of the SOA graph exemplifies how the dynamic pro- tection will cause waveform distortion when enabled. Auxiliary Amplifier Application Circuit. Operating graph in the Typical Performance Characteris. These instabilities can be eliminated through multiple.
Please refer to AN for more detailed information. Single Supply Application Circuit. Upon system power-up, the under-voltage protection cir. The LM is a stereo audio amplifier capable of delivering. An incorrect maximum power dissipation calculation may result in inad- equate heat sinking causing thermal shutdown and thus lim- iting the output power. 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 maximum theoretical point that results from Equation 1.
However, to improve system. Single Supply Amplifier Application Circuit. SPiKe Protection means that these. The LM contains over-voltage protection circuitry that.
The thermal resistance from the die junction to the outside. Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can be calcu- lated. The clamping effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes. Numbers in parentheses represent pinout for amplifier B.
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.

The LM is protected from instantaneous peak. However, to improve system performance as well as eliminate possible oscillations, the LM should have its supply leads bypassed with low-inductance capacitors having lm476t leads that are lo- cated close to the package terminals. The LM has excellent power supply rejection and does.
