16-22Bit 97dB Stereo Audio CODEC with Linein/Digital and Analog Microphone Recording, Lineout/Headphone/Speaker Playback, SMIC 65nmll
The AR82S01 is a silicon-proven, low-power, ultra compact 16-22bit stereo audio CODEC IP fabricated in SMIC 65nmll logic process. The CODEC IP core employs multi-bit sigma-delta architecture and digital filters for A/D and D/A conversion. It supports line-in, analog or digital microphone recording, line-out, headphone, and speaker phone playback. The CODEC operates in master or slave mode with standard digital audio interface. The CODEC is suitable for cost-effective low power voice/audio applications.
