Rohm Audio D/A Converter ICs
An audio digital-to-analog converter (DAC) is an integrated circuit (IC) that converts a digital audio signal into an analog electrical signal. Audio DAC ICs are used in digital audio equipment such as CD players, digital music/audio servers, and other digital audio equipment. These ICs convert a digital audio signal into an analog audio signal with a specific number of bits per sample, such as 8-bit or 16-bit. The resolution of the DAC dictates the quality of the analog audio output. Higher resolution audio converters offer improved audio accuracy and better sound quality. Audio DAC ICs typically include one or more inputs (ADC), an analog-to-digital converter (DAC), support for multiple audio formats, and a voltage reference. Some DAC ICs may also provide built-in DSP functionality and dedicated signal processing blocks such as filters.
