Audio A/D Converter ICs
An audio A/D converter IC (integrated circuit) is a device that converts analog audio signals into digital audio signals. These ICs, which are also known as analog-to-digital converters (ADCs), are found in a wide variety of consumer electronics products, from high-end audio systems to portable media devices. They allow digital audio content to be stored and manipulated in digital form, and transmitted over digital networks. Audio A/D converters are usually built with a specific resolution and sampling rate, allowing them to provide the specific digital data format that a particular system needs. In addition, the IC usually has circuitry to reduce noise and distortion in the analog audio signal, and to perform other useful operations such as volume control.
