Audio Amplifier ICs

Audio Amplifier ICs (integrated circuits) is a type of audio amplifier that is built into the chassis of the main product. More generally, audio amplifiers are devices that increase, control and amplify the audio signal strength, or amplitude, of audio signals, to make the sound louder and premium quality.

IC Audio amplifiers are useful because they can vastly decrease the size of amplification devices, making it possible to create sophisticated amplification within a small package. Unlike power amplifiers, they are not standalone devices.

What are the IC audio amplifiers used for?
Audio amplifier ICs are used in a range of commercial products. They are found in car stereos, televisions, electronic keyboards, and many other devices in which amplification capacity is in-built.

Types of audio amp ICs
Audio amplifier ICs can be differentiated by several traits:

• amplifier type, such as digital, operational, or headphone amps
• maximum power, in watts, depending on the size and scope of amplification you need
• input and output signal type, depending on whether you want stereo or mono sound
