GENERAL DESCRIPTION
The AD1984B audio codec and SoundMAX
® software provide
superior high definition audio quality that exceeds Vista Pre-
mium performance. The AD1984B has two 192 kHz DAC pairs,
two 192 kHz ADC pairs, dual S/PDIF outputs, a 2-channel digi-
tal microphone interface, and digital and analog PCBeep. These
features make the AD1984B the right choice for desktop and
notebook PCs where performance is key. For more information
