DATASHEET
STAC9227/9228/9229/9230
Description
The STAC9227/9228/9229/9230 are a family of Theater
Quality 8-channel audio CODECs that enable systems with
7.1 audio or 5.1 audio playing simultaneously with VoIP or
another stereo audio stream. SigmaTel's proprietary Σ∆
technology provides high fidelity with an estimated DAC
SNR up to 105dB. Up to four digital microphones are
supported enabling high quality voice input for increased
usability of voice applications.
