What Are The Best Resistors For Audio Equipment? - …
https://www.noisylabs.com/what-are-the-best-resistors-for-audio-equipment/
The most important factor when choosing a resistor is power. The best practice for finding the right resistor for your audio equipment is to find a resistor which doubles in power. To find power in a resistor use this formula: P=V squared/R. The P in the equation is power, while the V is for voltage, and the R stands for resistance.
Design a class AB audio amplifier - Electrical Engineering ...
https://electronics.stackexchange.com/questions/529475/design-a-class-ab-audio-amplifier
I am required to design a class AB audio amplifier to deliver 10W to an 8Ω speaker as shown, but I don't know where to start. The bandwidth is to cover the range from 20Hz to 18kHz. Input voltage is 500mV rms. Image source: Electronics Tutorials - Class AB Amplifier Driver Stage. This is what I have done so far.
Class AB Audio Amplifier | HACK A WEEK
http://hackaweek.com/hacks/class-ab-audio-amplifier/
Class AB Audio Amplifier. This week we’ll take a look at another type of audio amplifier, the class AB amp. As we saw in Hack #19 the class A amp has a transistor that is biased with a voltage that makes it essentially stay turned on all the time. This single transistor handles the entire waveform both positive and negative.

The Bulk Metal foil resistor is the preferable choice for audio amplifiers when high linearity of amplification and minimal dynamic distortion are required. In particular, Vishay Precision Group recommends the VAR, Z201, S102C, Z203, VSHZ, VSMP Series (0603-2018), VFCP Series, SMRXDZ Series resistors for noise-free performance in audio applications ( …

I'm building a PCB using an Atmega1284 (essentially it's an Arduino) and have need of an audio amplifier. Previously, I was using a very simple amplifier arrangement using a single transistor and an 8ohm speaker. Schematic below: However, using a single 150mah lipo battery, the battery would only last on average for 40 minutes.

In order for the audio amplifier to function properly, all of the components need to be in good working order. To keep them there, specific components cannot exceed certain power dissipations. All of the resistors except for the output resistor can only handle 0.250 Watts. All of
Designing an Opamp Headphone Amplifier. – HeadWize Memorial

Because a few milliwatts will drive headphones to full volume, a great headphone amplifier design can be relatively simple. Yet, there are any number of reasons for experimenting with more complex topologies, such as improved performance and the ability to incorporate custom options. Of course, some DIYers like to try different circuits just for the…
