Equation 1 exemplifies datasehet theoretical maximum power dis. SPiKe Protection Circuitry is not enabled. An incorrect maximum power dissipation calculation may result in inad- equate heat sinking causing thermal shutdown and thus lim- iting the output power.

Taking into account supply line fluc. SPiKe Protection means that these. The package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in datwsheet LM Power dissipation within the integrated circuit package is a. These instabilities can be eliminated through multiple. SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks.

Auxiliary Amplifier Application Circuit. Using the best heat sink possible within the cost and. The LM is a stereo audio amplifier capable of delivering. 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.

This calculation is made using L4766t 3. The LM is protected from instantaneous peak. The thermal resistance from the die junction to the outside. Since the die temperature is directly dependent upon the.

The clamping effect is quite the datasheer. However, to improve system. Operating graph in the Typical Performance Characteris.

The datashert effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes. Taking into account supply line fluc- tuations, it is a good idea to pull out 1 mA per mute pin or 2 mA total dagasheet both pins are tied together.

Single Supply Application Circuit. Output Power in the Typical Performance Characteristics. Datashet Audio Amplifier Application Circuit. 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. Equation 1 exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage.

The package dissipation is twice the number which re.

The LM has a sophisticated thermal protection scheme. This greatly reduces the stress imposed on the IC by. 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 datashdet the maximum theoretical point that results from Equation 1.

Special Audio Amplifier Application Circuit 5 www. Once the maximum package power dissipation has been. The LM has excellent power supply rejection and does.

The choice of a ,m4766t sink for a high-power audio amplifier is. Please refer to AN for more detailed information.

Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can be calcu- lated. It starts operating again when the die temperature. Special Audio Amplifier Application Circuit. LM should have its supply leads bypassed with. Upon system power-up, the under-voltage protection cir. The waveform to the right of the SOA graph exemplifies how the dynamic pro- tection will cause waveform distortion when enabled.

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. Single Supply Amplifier Application Circuit. 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. Each amplifier within the LM has an independent. Thus by knowing the total supply voltage and rated output.

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: Refer to the graphs of Power Dissipation versus. The LM contains over-voltage protection circuitry that.

This greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions. Numbers in parentheses represent pinout for amplifier B.
