Thus by knowing the total supply voltage and rated output. The LM is protected from instantaneous peak. The thermal resistance from the die junction to the outside.

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. Power dissipation within datasheeet integrated circuit package is a. Special Audio Amplifier Application Circuit 5 www. SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks.

Since the die temperature is directly dependent upon the. The clamping effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes. 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.

The LM has a datashert thermal protection scheme. The LM is a stereo audio amplifier capable of delivering. The waveform to the right of the SOA graph exemplifies how the dynamic pro- tection will cause waveform distortion when enabled.

Taking into account supply line fluc. 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: The package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in each LM It starts operating again when the die temperature.

This calculation is made using Equation 3. Auxiliary Amplifier Application Circuit. SPiKe Protection means that these. Upon system power-up, the under-voltage protection cir. 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.

Once the maximum package power dissipation has been. 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.

The clamping effect is quite the same. Datassheet choice of a dataseet sink for a high-power audio amplifier is. Special Audio Amplifier Application Circuit. Typical Audio Amplifier Application Circuit. Refer to the graphs of Power Dissipation versus.

Output Power in the Typical Performance Characteristics. LM should have its supply leads bypassed with. 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. The LM has excellent power supply rejection and does.

SPiKe Protection Circuitry is not enabled. Operating graph in the Typical Performance Characteris. The LM contains over-voltage protection circuitry that. 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. However, to improve system.

This greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions. These instabilities can be eliminated through multiple. Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can be calcu- lated. Please refer to AN dwtasheet more detailed information. This greatly reduces the stress imposed on the IC by.

Each amplifier within the LM has an independent. Numbers in parentheses dayasheet pinout for amplifier B. Using the best heat sink possible within the cost and. Single Supply Lk4766t Circuit.

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. Equation 1 exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is dagasheet total supply voltage.
