CM102S+

Product Summary

The CM102S+ is a USB Stereo Audio Chip for Speaker Integrated. Minimum external components are needed for building an USB speaker system, which makes the CM102S+ a simple and very cost-effective solution. Since no driver is necessary for audio playback on all major OS. The CM102S+ provides a truly plug-and-play feature for external digital audio playback.
