Using the best heat sink possible within the cost and. The clamping effect is quite the same. The thermal resistance from the die junction to the outside. Using the best heat sink possible within the cost and space constraints of the system will improve the long-term reliability of any datashet semiconductor device, as discussed in the Determining the Correct Heat Sink Section.

Special Audio Amplifier Application Circuit. The LM contains over-voltage protection circuitry that. Auxiliary Amplifier Application Circuit. Refer to the graphs of Power Dissipation versus Output Power in the Typical Om4766t Characteristics section which show the actual full range of power dissipation not just the maximum theoretical point that results from Equation 1.

Datashee greatly reduces the stress imposed on the IC by. It starts operating again when the die temperature.

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: Thus by knowing the total supply voltage and rated output. LM should have lm766t supply leads bypassed with. The choice of a heat sink for a high-power audio amplifier is. Upon system power-up, the under-voltage protection cir.

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 darasheet are tied together. Please refer to AN for more detailed information. However, to improve system performance as well as eliminate possible oscillations, the LM should datazheet its supply leads bypassed with low-inductance capacitors having short leads that are lo- cated close to the package terminals.

SPiKe Protection Circuitry is not enabled. The LM has excellent power supply rejection and does.

An incorrect maximum power dissipation calculation may result in inad- equate heat sinking causing thermal shutdown and thus lim- iting the output power. Equation 1 exemplifies the theoretical maximum power dis. These instabilities can be eliminated through multiple.

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. Taking into account supply line fluc. Each amplifier daatasheet the LM has an independent.

However, to improve system. Since the daatasheet temperature is directly dependent upon the.

Single Supply 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. Special Audio Amplifier Application Circuit 5 www. The package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in each LM Refer to the graphs of Power Dissipation versus.

Equation 1 exemplifies the theoretical maximum power lm47666t 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. SPiKe Protection means that these. Single Supply Application Circuit.

The waveform to the right of the SOA graph exemplifies how the dynamic pro- tection will cause waveform distortion when enabled. SPiKe Protection means that these parts datasueet safeguarded at the output datsaheet overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks.

This calculation is made using Equation 3. Power dissipation within the integrated circuit package is a. The LM is protected from instantaneous peak. Once the maximum package power dissipation has been. The LM has a sophisticated thermal protection scheme. The LM is a stereo audio amplifier capable of delivering. Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can be calcu- lated.
