GENERAL DESCRIPTION
The AD1882A audio codec and SoundMAX(R) software provides superior HD audio quality that exceeds Vista Premium performance. The AD1882A has six DACs and four ADCs, two stereo headphone ports, C/LFE swapping, digital and analog PCBeep, and S/PDIF output, making the AD1882A the right choice for desktop and notebook PCs where performance is the primary consideration. The jack retasking feature on this product supports various configurations including platforms for 5.1 on 5 or 3 jacks, and front panel jack retasking. The AD1882A is available in a 48-lead Pb-free lead frame chip scale package in both reels and trays. See Ordering Guide on Page 17.
