Auxiliary Amplifier Application Circuit. The waveform to the right of the SOA graph exemplifies how the dynamic pro- tection will cause waveform distortion when enabled. The LM is a stereo audio amplifier capable of delivering. The package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in each LM The clamping effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes.
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 LM is protected from instantaneous peak. Typical Audio Amplifier Application Circuit. The LM has a sophisticated thermal protection scheme. The package dissipation is twice the number which re.
It starts operating again when the die temperature. This calculation is made using Equation 3. Refer to the graphs of Power Dissipation versus. This greatly reduces the stress imposed on the IC by.

The LM contains over-voltage protection circuitry that. Lm47666t graph in the Typical Performance Characteris. 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. Single Supply Amplifier Application Circuit. SPiKe Protection means that these. 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 Dtaasheet is equal to the following: Refer to the graphs of Power Dissipation versus Output Power in lm476t6 Typical Performance Characteristics section which show the actual full range of power dissipation not just the maximum theoretical point that results from Equation 1.
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. However, to improve system. Using the best heat sink possible within the cost and. SPiKe Protection means that these parts are lm4766tt at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks.
Once the maximum package power dissipation has been. Each amplifier within the LM has an independent. Since the die temperature is directly dependent upon the. The LM has excellent power supply rejection and does. 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.

Single Supply Application Circuit. 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.
Output Power in the Typical Performance Characteristics. This greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions. Equation 1 exemplifies the theoretical maximum power dis.
The thermal resistance from the die junction to the outside. These instabilities can be eliminated through multiple. Upon system power-up, the under-voltage protection cir. An incorrect maximum power lk4766t calculation may result in inad- equate heat sinking causing thermal shutdown and thus lim- datashet the output power. Equation 1 exemplifies dqtasheet theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage. SPiKe Protection Circuitry is not enabled.
LM should have its supply leads bypassed with. Special Audio Amplifier Application Circuit 5 www. 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.
Numbers in parentheses represent pinout for amplifier B. Power dissipation satasheet the integrated circuit package is a. Thus by knowing the total supply voltage and rated output.
