The STAC9766/9767 incorporates IDT's proprietary Σ∆ technology The AC’97 CODEC is designed to achieve a DAC SNR in excess of 103dB.
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 STAC9766/9767 includes digital input/output capability for support of modern PC systems with an output that supports the SPDIF format.
The STAC9766/9767 is a standard 2-channel stereo CODEC.
With IDT’s headphone drive capability, headphones can be driven with without an external amplifier.
The STAC9766/9767 may be used as a secondary CODEC, with ...
