The ALC882 series 7.1+2 Channel High Definition Audio codecs with UAA (Universal Audio Architecture), featuring five 24-bit stereo DACs and three 20-bit stereo ADCs, are designed for high performance multimedia PC systems.
The ALC882 series incorporates proprietary converter technology to achieve over 100dB Signal-to-Noise ratio playback quality; easily meeting PC2001 requirements and also bringing PC sound quality closer to consumer electronic devices.

The ALC882 series provide 10 channels of DAC that simultaneously support 7.1 sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the Front-Out-Left and Front-Out-Right channels. Flexible mixing, mute, and fine gain control functions provide a complete integrated audio solution for next generation multimedia PCs.
