Realtek PDF datasheet ALC231 for free download

Designed for the following chipset:
- ALC231-CG

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.

The ALC231 headphone amplifier can drive a 32Ω headphone load without external DC blocking capacitors, eliminating pop noise caused by these capacitors. In addition to the cap-free headphone output port (HP-OUT), the LINE-OUT port is also designed as a line-level output without the need for DC blocking capacitors, eliminating pop noise when connecting to external powered speakers.

The integrated mono Class-D amplifier directly drives a mini speaker with as low as 4Ω impedance. Its maximum output power is 2 Watts at 5V power supply. The built-in high-pass filter with configurable cut-off frequency can prevent speaker burn up caused by low-frequency sound. The Class-D amplifier output power can also be limited to prevent mini speaker damage.

The ALC231 has overcurrent and short circuit detection to protect the integrated Class-D amplifier and power system. The Class-D amplifier output will be automatically shut down when a connected speaker is disconnected or to prevent over-heating. As well as protection functions, the ALC231 features spread spectrum and slew rate control for the Class-D carrier frequency to reduce EMI radiation.

Support for 16/20/24-bit SPDIF output with up to 192kHz sample rate offers easy connection of PCs to consumer electronic products, or transport of digital audio output to a High Definition Media Interface (HDMI) transmitter.

The ALC231 supports host audio from Intel chipsets, and also from any other HDA compatible audio controller. With various software utilities like environment sound emulation, multiple-band and independent software equalizer, dynamic range compressor and expander, optional Dolby PCEE program, SRS TruSurround HD, SRS Premium Sound, Fortemedia SAM, Creative Host Audio, Synopsys Sonic Focus, DTS Surround Sensation | UltraPC, and DTS Connect licenses, the ALC231 offers high sound quality, providing an excellent entertainment package and game experience for PC users.
