The LM is a high-performance audio power amplifier capable of delivering 40W of continuous average power to an 8Ω load with % THD+N from.
I used a protoboard for my amplifier details below. Only one channel is shown. A double pole, double throw DPDT switch is shared between both channels and this allows switching the output between speakers output or headphone output.
If you do not need a headphone output, you can eliminate the DPDT switch and the resistors after the switch. The gain of the circuit is 33 30 dB which should work well for most line level sources.
This project requires a mains wiring connection or V which you do not want to get in between. Faulty or incorrect mains wiring can result in death or serious injury! Please refer to your local electrical code for the mains connection requirements.
Use appropriate fuses and connect the chassis to the mains "earth". A torroidal transformer with dual 18 Volt secondaries and rated at VA 3. Output Power Figure.
Frequency Figure Distortion vs. Frequency Figure Quiescent Current vs. Frequency Single supply for Different values of C2 circuit of fig.
The maximum output current is a function of the collector emitter voltage; hence the output transistors work within their safe operating area.
This function can therefore be considered as being peak power limiting rather than simple current limiting.
TDA2050V 32-Watt Audio Amplifier
It reduces the possibility that the device gets damaged during an accidental short circuit from AC output to ground. Figure Total Power Dissipation and Efficiency vs.
There is no possibility of device damage due to high junction temperature. If for any reason, the junction temperature increases up to C, the thermal shutdown simply reduces the power dissipation and the current consumption.
Figure Maximum Allowable Power Dissipation vs. Ambient Temperature cient. Between the heatsink and the package is better to insert a layer of silicon grease, to optimize the thermal contact; no electrical isolation is needed between the two surfaces.
Dimension suggestion The following table shows the length that the heatsink in fig. We give here only a brief extract of the concept, and a circuit useful for the measurement.Use appropriate fuses and connect the chassis to the mains "earth". If you do not need a headphone output, you can eliminate the DPDT switch and the resistors after the switch.
One thing to note is that the gain of the circuit needs to be at least 24dB to maintain stability.
Figure Total Power Dissipation and Efficiency vs. This is well beyond any human hearing range so I fail to see how this could be considered an issue. Contrast that to class AB and similar amplifiers.
