ENGLISH DATASHEETS for Realtek ALC269
Realtek ALC269 (sound chip)
Release: 1.5 from 2009-07-20

Designed only for Realtek ALC269Q-GR ALC269QSRS-GR ALC269W-GR
The ALC269 is a High Definition Audio Codec that integrates a 2+2-channel DAC, a 4-channel ADC, and a Class-D Speaker Amplifier.

The 2+2-channel DAC supports two independent stereo sound outputs simultaneously. The 4-channel ADC integrates two stereo and independent analog sound inputs (multiple streaming).

The ALC269 incorporates Realtek converter technology to achieve a 98dB dynamic range playback quality and a 98dB dynamic range recording quality. It meets the current WLP3.10 (Windows Logo Program) and future WLP requirements.

The ALC269 also supports stereo digital microphone channels (microphone array) with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technology simultaneously, significantly improving voice quality for PC VoIP applications.

As well as basic audio functions, the ALC269 has two independent S/PDIF outputs; one could be used to connect a PC to high-quality consumer electronic products such as digital decoders and speakers, the other could provide a dedicated digital output to a HDMI transmitter (common in high end PCs).

There are three integrated power amplifiers. The first is a linear headphone amplifier at port C. The second headphone amplifier at port A removes the need for external DC blocking capacitors, eliminating pop noise caused by these capacitors. The third is an integrated stereo Class-D amplifier to directly drive a mini-speaker. The Class-D amplifier is designed to drive speakers with as low as 4Ω impedance. Its maximum output power is 2.3W per channel at 5V power supply. The advantage of an integrated Class-D amplifier in the ALC269 is high efficiency with low power consumption.

The ALC269 integrates five hardware equalizer bands composed of one low-pass filter, one high-pass filter, and three band-pass filters to compensate for mini-speaker frequency response. All the equalizer filters are programmable via the BIOS, allowing the equalizer to function without the need to customize the audio driver.

The ALC269 conforms to Intel’s Audio Codec low power state white paper and is ECR compliant.
