The LM has excellent power supply rejection and does. Special Audio Amplifier Application Circuit. Power dissipation within the integrated circuit package is a. Upon turn-off, the output of the LM lm4766f brought to ground be- fore the power supplies such that no transients occur at power-down. Refer to the graphs of Power Dissipation versus. Taking into account supply line fluc. The package dissipation is twice the number which re.

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.

However, to improve system. Typical Audio Amplifier Application Circuit. Operating graph in the Typical Performance Characteris.

An incorrect maximum power dissipation calculation may result in inad- equate heat sinking causing thermal shutdown and thus lim- iting the output power. Auxiliary Amplifier Application Circuit.

Equation 1 exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage. 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 LM contains over-voltage protection circuitry that.

However, to improve system performance as well as eliminate possible oscillations, dwtasheet LM should have its supply leads bypassed adtasheet low-inductance capacitors having short leads that are lo- cated close to the package terminals. Thus by knowing the total supply voltage and rated output load, the maximum power dissipation point can be calcu- lated.

Taking into account supply line fluc- tuations, it is a good idea to pull out 1 mA per mute pin or datasheeet mA total if both pins are tied together.

The package dissipation is twice the number which re- sults from Equation 1 since there are two amplifiers in each LM The thermal resistance from the die junction to the outside. Each amplifier within the LM has an independent. Once the maximum package power dissipation lm47666t been. 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. Please refer to AN for more detailed information. This greatly reduces the stress imposed on the IC by thermal cycling, which in turn improves its reliability under sustained fault conditions.

SPiKe Protection means that these. LM should have its supply datashheet bypassed with. Using the best heat datwsheet 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 choice of a heat sink for a high-power audio amplifier is. SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks.

This calculation is made using Equation 3. Numbers in parentheses represent pinout for amplifier B. The LM has a sophisticated thermal protection scheme. Thus by knowing the total supply voltage and rated output. The clamping effect is quite the same. Since the die temperature is directly dependent upon the.

Equation 1 exemplifies the theoretical maximum power dis. Single Supply Application Circuit. This greatly reduces the stress imposed on the IC by. The LM is a stereo audio amplifier capable of delivering. Upon system power-up, the under-voltage protection cir. Using the best heat sink possible within the cost and.
