GENERAL DESCRIPTION
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.
