Product Summary
IDT's STAC9750/9751 are general purpose, full duplex, audio CODECs conforming to the analog component spec- ification of AC'97 (Audio CODEC 97 Component Specifica- tion Rev. 2.2). They have 18-bit ADCs and 20-bit DACs. The STAC9750/9751 incorporate IDT's proprietary Σ? tech- nology to achieve a DAC SNR in excess of 89dB. 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. The STAC9750/9751 include digital input/output capability for support of modern PC systems and also an output that supports the SPDIF format. The STAC9750/9751 is a standard 2-channel stereo CODEC. With IDT’s headphone drive capability, head- phones can be driven with no external amplifier
