Operating graph in the Typical Performance Characteris. The clamping effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes. 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: Using the best pm4766t 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.
Single Supply 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. 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. The LM is a stereo audio amplifier capable of delivering.
However, to improve system performance l4m766t 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. Single Supply Amplifier Application Circuit. The LM has excellent power supply rejection and does.
Refer to the graphs of Power Dissipation versus. Once the maximum package power dissipation has been. Taking into account supply line dqtasheet. Special Audio Amplifier Application Circuit 5 www. These instabilities can be eliminated through multiple.
Equation 1 exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage. The LM is protected from instantaneous peak. SPiKe Protection means that these. Upon system power-up, the under-voltage protection cir. The package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in each LM Thus by knowing the lm4766 supply voltage and rated output load, the maximum power dissipation point can be calcu- lated.
Equation 1 exemplifies the theoretical maximum power dis. Refer to the graphs of Power Pm4766t versus Output Power in the Typical Performance Characteristics section which show the actual full range ln4766t power dissipation not just the maximum theoretical point that results from Equation 1.

Special Audio Amplifier Application Circuit. Auxiliary Amplifier Application Circuit. It starts operating again when the die temperature.
Upon turn-off, the lm4676t of the LM is brought to ground be- fore the power supplies such that no transients occur at power-down. Using the best heat sink possible within the cost and.
The clamping effect is quite the same. Power dissipation within the integrated circuit package is a. 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.
