GENERAL DESCRIPTION
Featuring four 16-bit two-channel DACs and a stereo 16-bit ADC, Four pairs of stereo outputs, with 5-bit volume control and multiple stereo and mono inputs, along with flexible mixing, and gain and mute functions, provide a complete integrated audio solution for PCs. Two integrated 50mW/20ohm headphone audio amplifiers provide high-quality personal audio listening. Utilizing Universal Audio Jack® technology, Line-In and Mic-In can also serve as an amplified stereo Headphone-Out. In addition, the ALC850(D) is embedded with an impedance sensing capability to detect when a device has been connected to input or output jacks. The ALC850(D) integrates an on-board dual PLL clock generator (14.318MHz and 24.576MHz), saving the cost of a 24.576MHz crystal. A PCBEEP generator is built-in and can be programmed by the BIOS to generate POST beeps without a buzzer. S/PDIF input and output functions are also supported, offering easy connection of PCs to consumer electronic products such as AC3 decoders/speakers, and mini disk devices.
