Integrating Mixed-Signal Solutions DATA SHEET STAC9721/23 Stereo AC'97 Codec With Multi-Codec Option GENERAL DESCRIPTION: SigmaTel’s STAC9721/23 is a general-purpose 18-bit stereo, full duplex, audio codec that conforms to the analog component specification of AC'97 (Audio Codec 97 Component Specification Rev. 2.1). The STAC9721/23 incorporates SigmaTel’s proprietary Sigma-Delta technology to achieve a DAC SNR in excess of 95dB. The DACs, ADCs, and mixer are integrated with analog I/Os, which include four analog line-level stereo inputs, two analog line-level mono inputs, two stereo outputs, and one mono output channel. Also included are SigmaTel’s 3D stereo enhancement (SS3D), and an extra true line-level out for headphones or speaker amplifiers.
