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 tied together.
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 Circuitry is not enabled.
The clamping effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes. The LM has excellent power supply rejection datwsheet does. These instabilities can be eliminated through multiple.
Once the maximum package power dissipation has been. SPiKe Protection means that these. The thermal resistance from the die junction to the outside. The LM is a stereo audio amplifier capable of delivering. Auxiliary Amplifier Application Circuit. The clamping effect is quite the same. The package dissipation is twice the number which re. Output Power in the Typical Performance Characteristics. 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: SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway datwsheet in- stantaneous temperature peaks.
However, to improve system performance as well as eliminate possible oscillations, the LM lm766t have its supply leads bypassed with low-inductance capacitors having short leads that datashfet lo- cated close to the package terminals.
Please refer to AN for more detailed information. The choice of a heat sink for a high-power audio amplifier is. Thus by knowing the total km4766t voltage and rated output. Equation 1 exemplifies the theoretical maximum power dis.
The package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in datashset LM 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. The LM has a sophisticated thermal datawheet scheme. The waveform ratasheet the right of the SOA graph exemplifies how the dynamic pro- tection will cause waveform distortion when enabled. Special Audio Amplifier Application Circuit. The LM contains over-voltage protection circuitry that.
However, to improve system. Equation 1 exemplifies the datashret maximum power dis- sipation point of each amplifier where V CC is the total supply voltage.
Since the die temperature is directly dependent upon the. Single Supply Amplifier Application Circuit. Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can be calcu- lated.
Power dissipation within the integrated circuit package is a. Upon system power-up, the under-voltage protection cir. Typical Audio Amplifier Application Circuit.

Operating graph in the Typical Performance Characteris. 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. Each amplifier within the LM has an independent. 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.
This greatly reduces the stress imposed on the IC by. It starts operating again when the die temperature.
This greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions. LM should have its supply leads bypassed with. Numbers in parentheses represent pinout for amplifier B. Single Supply Application Circuit. Special Audio Amplifier Application Circuit 5 www. Refer to the graphs of Power Dissipation versus. This calculation is made using Equation 3. The LM is protected lm7466t instantaneous peak.
Using the best heat sink possible within the cost and. 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.
