OPA134 series are ultra-low distortion, low noise operational amplifiers fully specified for audio applications. A true FET input stage is also incorporated to provide superior sound quality and speed for exceptional audio performance. This in combination with high output drive capability and excellent dc performance allows use in a wide variety of demanding applications. The IC also offers many different features such as high input impedance and high noise immunity.
Audio Operational Amplifier
An audio power amplifier is an electronic amplifier that amplifies low-power audio signals such as, the signal from a radio receiver or an electric guitar to a level that is strong enough for driving loudspeakers or headphones. Different kinds of sound systems such as sound reinforcement systems, public address, home audio systems & musical instrument amplifiers like guitar amplifiers use different types of audio amplifiers.
