GENERAL DESCRIPTION

The ALC250 CODEC provides two pairs of stereo outputs with independent volume controls, a mono output, and multiple stereo and mono inputs, along with flexible mixing, gain, and mute functions to provide a complete integrated audio solution for PCs. The circuitry of the ALC250 CODEC operates from a +3.3V digital power and +5V analog power supply with EAPD (External Amplifier Power Down) control for use in notebook and PC applications. The ALC250 integrates a 50mW/20Ω headset audio amplifier into the CODEC, saving BOM costs. The ALC250 also supports the SPDIF out function, which complies with AC'97 2.3, and offers easy connection of PCs to consumer electronic products, such as AC3 decoder/speaker and mini disk devices. The ALC250 CODEC supports host/soft audio from Intel ICHx chipsets as well as audio controller based VIA/SIS/ALI/AMD/nVIDIA/ ATI chipset.
