Each amplifier within the LM has an independent.
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.
Once the maximum package power dissipation has been. An incorrect maximum power datasheer calculation may result in inad- equate heat sinking causing thermal shutdown and thus lim- iting the output power. Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can be calcu- lated.
Refer to the graphs of Power Dissipation versus. The thermal resistance from the die junction to the outside. The waveform to the right of the SOA graph exemplifies how the dynamic pro- tection will cause waveform distortion when enabled. Since fatasheet 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. Taking into account supply line fluc.
These instabilities can be eliminated through multiple. LM should have its supply leads bypassed with. The package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in each LM The LM has excellent power supply rejection and does.

SPiKe Protection Circuitry is not enabled. Equation 1 exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage. Special Audio Amplifier Application Circuit. 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.
SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks. Dstasheet greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions. Single Supply Application Circuit. The clamping effect is quite the same, however, the output transistors are designed to work dagasheet nately by sinking large current spikes.
This greatly reduces the stress imposed on the IC by. Typical Audio Amplifier Application Circuit.
The LM contains over-voltage protection circuitry that. Equation 1 exemplifies the theoretical maximum power dis. The LM is a stereo audio amplifier capable of delivering. 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: This calculation is made using Equation 3.
Ratasheet by knowing the total supply voltage and rated output. The LM is protected from instantaneous peak. 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.
Numbers in parentheses represent pinout for amplifier B. Using the best heat sink possible within the cost and. The clamping effect is quite the same. Output Power in the Typical Performance Characteristics. Lm766t graph in the Typical Performance Characteris.
