Which transistor is best for audio amplifier?

Best Transistors: BJTs

#1 NPN – 2N3904. You can find most often NPN Transistors in low-side switch circuits.
#2 PNP – 2N3906. For high-side switch circuits, you need a PNP style BJT.
#3 Power – TIP120.
#4 N-Channel (Logic Level) – FQP30N06L.

Can you use Mosfet as an audio amplifier?

Mosfet is a good choice for building linear amplifiers owing to its lesser load, and any amplifier made using it is called a Mosfet amplifier. These amplifiers have a wide range of applications, they can be used in many circuits.

What is an audio amplifier circuit?

The circuit of the audio amplifier consists of a transistor a device to apply the input signals and a speaker at the output. The transistors are connected based on the necessity. The important factors that need to be considered while designing a audio amplifier is gain,noise, frequency response and distortion.

How can I make my audio amplifier better quality?

Improving the following factors will undoubtedly enhance the potential sound quality of the system.

Speakers. One of the best ways to improve sound quality is to replace lower-quality speakers with higher-quality speakers rather than the amplifier itself.
Speaker Position.
Room Acoustics.
Audio Format/Quality.
Equalization.

Which is better amplifier BJT or Mosfet?

BJTs tend to have better, more linear gain characteristics and can give you a lot higher voltage gain than MOSFETs. They’re also able to handle higher output currents and have a lower output impedance.

Is LM386 an op-amp?

The LM386 is an operational amplifier than has been specifically designed for use in audio applications… which means its performance is based on the assumption that it will be driving speakers. At least at some point. However it can, like most other basic audio amplifier chips, be used as a regular op-amp as well.
