ALC880 Series
Datasheet
1. General Description
The ALC880* and ALC880D** 7.1 Channel High Definition Audio codecs with UAA (Universal Audio
Architecture), featuring four 24-bit two-channel DACs and three stereo 20-bit ADCs, are designed for
high performance multimedia PC systems. The ALC880(D) incorporates proprietary converter
technology to achieve 95dB sound quality; easily meeting PC2001 requirements and also bringing PC
sound quality closer to consumer electronic devices.
The ALC880(D) provides 7.1 output channels, along with flexible mixing, mute, and fine gain control
functions to provide a complete integrated audio solution for PCs. The DACs (with a highest sampling
frequency of 192kHz) and Realtek proprietary hardware content protection are applicable for
DVD-Audio, previously only implemented in high-end consumer electronics, and now achieved by PCs
with the ALC880(D) inside. The ALC880(D) also integrates three stereo ADCs that can support a
microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression
(NS) technology simultaneously, significantly improving recording quality for conference calls. With this
feature (3 stereo ADCs), the ALC880(D) can provide high-quality audio using S/PDIF to output analog
data, or for multiple-source recording applications.
Realtek’s proprietary impedance sensing and jack detect techniques allow device loads on inputs and
outputs to be auto-detected. All analog IO are input and output capable, and headphone amplifiers are
also integrated at each analog output. All analog IOs can be re-tasked according to user’s definitions, or
automatically switched depending on the connected device type (Universal Audio Jack®).
The ALC880(D) supports 32-bit S/PDIF input and output functions and a sampling rate of up to 96kHz,
offering easy connection of PCs to high quality consumer electronic products such as AC-3
decoders/speakers, and mini disk devices.

The ALC880(D) supports host/soft audio from the Intel ICH6 chipset, and also from any other HDA
compatible audio controller. With EAX/Direct Sound 3D/I3DL2/A3D compatibility, and excellent
software utilities like Karaoke mode, environment emulation, software equalizer, HRTF 3D positional
audio, and optional Dolby® Digital Live, the ALC880(D) provides an excellent entertainment package
and game experience for PC users.
*Note: The ALC880 series covers all products listed in section 12 Ordering Information, page 74.
**Note: D indicates Dolby Digital Live (software feature)
