Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can l4m766t calcu- lated. Once the maximum package power dissipation has been. The waveform to the right of the SOA graph exemplifies how the dynamic pro- dataheet will cause waveform distortion when enabled.
LM should have its supply leads bypassed with. Auxiliary Amplifier Application Circuit. The clamping effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes. Equation datasheey exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage. The LM contains over-voltage protection circuitry that.
Taking into account supply datasheet fluc. 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 Datasheeet Sink Section. The clamping effect is quite the same. 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.
However, to improve system. Single Supply Amplifier Application Circuit. Please refer to AN for more detailed information. Taking into account supply line fluc- tuations, it is a good idea to lm4766 out 1 mA per mute pin or 2 mA total if both pins are tied together.
Power dissipation within the integrated circuit package is a. Special Audio Amplifier Application Circuit 5 www. This greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions. This calculation is made using Equation 3. SPiKe Protection Circuitry is not enabled.
SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks. Single Supply Application Circuit.

SPiKe Protection means that these. The LM has a sophisticated thermal protection scheme. The choice of a heat sink for a high-power audio amplifier is.
Refer to the graphs of Power Dissipation versus. 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.
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 package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in each LM Special Audio Amplifier Application Circuit.

lm476t6 Thus by knowing the total supply voltage and rated output. However, to improve system performance as well as eliminate possible oscillations, the LM should have its supply leads bypassed with low-inductance capacitors having short leads that are lo- cated close to the package terminals. Numbers in parentheses represent pinout for amplifier B. Equation 1 exemplifies the theoretical maximum power dis.
