Audio DACs

An Audio Digital-to-Analogue Converter (DAC) captures and converts high-quality digital audio to direct line level output analogue signal. On the other hand, when the goal is a conversion from analogue to digital, the best way to achieve that is via audio ADCs converters.

Selection specification includes the number of DAC channels, resolution in bits, sampling rate in kHz or Samples per a Second (SPS), analogue output in mono, stereo or multi-channel audio.
The control interface is managed through the SPI and I2C serial bus or hardware. The sampled analogue signals are digitally represented in the Pulse-Code Modulation (PCM) and I2S bus.

Differential outputs offer high precision. On-chip voltage reference is a special feature. The DAC output is perfectly suited for headphone amplifiers and Class-D, Class AB speaker amplifiers. Digital audio converting is found in applications of Digital Audio Broadcasting (DAB), High Definition (HD) Radio, digital media players, automotive audio systems, and audio video receivers.
