What is an Audio Amplifier?

Author:    Source:    Release time: 2016-06-23 12:02:36

An audio amplifier is an electronic device that increases the strength (amplitude) of audio signals that pass through it. An audio amplifier amplifies low-power audio signals to a level which is suitable for driving loudspeakers. The input signal of an audio amplifier may only measure a few hundred microwatts, but its output may be tens or even thousands of watts. Design parameters for audio amplifiers include gain, frequency response, distortion and noise.

Types of Audio Amplifiers

There are many different kinds of audio amplifiers and at Future Electronics we stock many of the most common types categorized by gain, nominal gain bandwidth, output power, maximum supply voltage, packaging type and number of channels. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for gain are 20 dB, 26 dB, 30 dB, 36 dB and 48 dB. We also carry audio amplifiers with gain as high as 115 dB. The number of channels can be between 1 and 10, with the most common audio amplifier semiconductor chips having 1, 2 or 4 channels.

Audio Amplifiers from Future Electronics

Future Electronics has a full selection of programmable audio amplifier chips from several manufacturers that can be used to design a home audio amplifier, mini audio amplifier, audio amplifier IC (integrated circuit), car audio amplifier, digital audio amplifier, inline audio amplifier, low power audio amplifier, PC audio amplifier, TV audio amplifier or stereo audio amplifier. Simply choose from the audio amplifier technical attributes below and your search results will quickly be narrowed to match your specific audio amplifier application needs.

If you have a preferred brand, we deal with several manufacturers such as New Japan Radio, NXP, ON Semiconductor, STMicroelectronics or Wolfson Microelectronics, among other manufacturers. You can easily refine your audio amplifier product search results by clicking your preferred audio amplifier brand below from our list of manufacturers.

Applications for Audio Amplifiers:

Applications for audio amplifiers include home audio systems, concert and theatrical sound reinforcement and public address systems. The sound card in a personal computer, every stereo system and every home theatre system contains one or several audio amplifiers. Other applications include instrument amplifiers such as guitar amplifiers, professional and amateur mobile radio and portable consumer products such as games and children’s toys.

Choosing the Right Audio Amplifier:

When you are looking for the right audio amplifiers, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by Nominal Gain Bandwidth (22 Hz, 20 kHz, 300 kHz,…), Gain (0 dB, 20 dB, 26 dB, 30 dB, 36 dB, 48 dB,…) and Output Power (27 mW to 200 W) to name a few. You will be able to find the right semiconductor chip from several manufacturers that can be used to design a mini audio amplifier, home audio amplifier, audio amplifier IC (integrated circuit), inline audio amplifier, low power audio amplifier, car audio amplifier, digital audio amplifier, PC audio amplifier, stereo audio amplifier, TV audio amplifier or any other devices requiring an audio amplifier.

Audio Amplifiers in Production Ready Packaging or R&D Quantities

If the quantity of audio amplifiers required is less than a full reel, we offer customers many of our programmable audio amplifier products in tube, tray or individual quantities that will avoid unneeded surplus.

In addition, Future Electronics offers clients a unique bonded inventory program that is designed to eliminate potential problems that may arise from an unpredictable supply of products containing raw metals and products with erratic or long lead times.
