PCM2704CDBR

The PCM2704CDBR is a USB-compatible digital-to-analog converter (DAC) from Texas Instruments. It integrates a USB 1.1 interface, supporting 16-bit/32kHz/44.1kHz/48kHz audio playback without requiring external drivers (plug-and-play).
Key features:
- USB-powered (no external power needed).
- Built-in digital S/PDIF output (for external DACs).
- Stereo line-level analog output (3.0Vpp).
- Low jitter clock recovery for improved audio quality.
Applications include USB audio adapters, headphones, and PC sound cards. The CDBR suffix denotes a SSOP-28 package.
Advantages:
✔ Simple USB audio solution.
✔ No firmware/driver requirements (Windows/Mac/Linux compatible).
Limitations:
✖ Limited to 16-bit/48kHz (not hi-res).
✖ USB 1.1 bandwidth restricts multi-channel use.
Ideal for budget-friendly USB audio interfaces where basic DAC functionality suffices.
