Since the die temperature is directly dependent upon the. 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 datashwet to the package terminals.

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

Single Supply Amplifier Application Circuit. Equation 1 exemplifies the theoretical maximum power dis- sipation point of each amplifier where V CC is the total supply voltage. The thermal resistance from the die junction to the outside. Equation 1 exemplifies the theoretical maximum power dis.

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 has excellent power supply rejection and does. Taking into account supply line fluc. Thus by knowing the total supply voltage and rated output. Numbers in parentheses represent pinout for amplifier B. Typical Audio Amplifier Application Circuit. 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 Each amplifier within the LM has an independent.

SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks.

The LM contains over-voltage protection circuitry that. Thus by knowing the total supply voltage and rated ln4766t load, the maximum power dissipation point can be calcu- lated.

National Semiconductor

This greatly reduces the stress imposed on the IC by. SPiKe Protection means that these. Please refer to AN for more detailed information. The choice of a heat sink for a high-power audio amplifier is.

This calculation is made using Equation 3. The clamping effect is quite the same, however, the output transistors are designed to work alter- nately by sinking large current spikes. 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.

The clamping effect is quite the same.
