DESCRIPTION
The DS4201 Universal Serial Bus (USB) audio device is a complete interface solution for USB based PC
digital audio playback. Integrating a USB device core, stereo 16–bit sigma–delta DAC and fixed function
DSP processing, as shown in Figure 1, the DS4201 is designed specifically for USB digital speaker
implementations. Digital–to–analog audio data processing supports 8 and 16–bit PCM stereo/mono
formats at 44.1 KHz and 48.0 KHz sampling rates. Additionally, analog output mixing of line and
microphone inputs provide legacy and hybrid speaker capabilities.
