The ALC231 is a High Definition Audio Codec that integrates a 4-channel DAC, 4-channel ADC, and a mono and filter-less Class-D Speaker Amplifier with 2Watt (rms) output power. The 4-channel DAC and 4-channel ADC support two independent stereo sound outputs and two independent stereo inputs simultaneously; allowing multiple streaming playback and output for multimedia applications and voice communication. The ALC231 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.
