16-22Bit Stereo Audio CODEC with Microphone / Line-in Recording, Lineout / Headphone Playback, SMIC 0.13um,
The AR34S4C is a silicon-proven, low-power, ultra compact 16-22bit stereo audio CODEC IP fabricated in SMIC130nm logic process. The CODEC IP core employs sigma-delta modulator architecture and digital filters for A/D and D/A conversion. The CODEC operates in master or slave mode with standard digital audio interface. The CODEC is suitable for low cost audio applications such as PMP, smart phone, MID, E-Book, and Web-TV.
