 AD1984
GENERAL DESCRIPTION
The AD1984 family of audio codecs and SoundMAX® software
provides superior High Definition audio quality that exceeds
Vista Premium performance. The AD1984 has four 192 kHz
DACs, four 192 kHz ADCs, S/PDIF output, a four-channel digi-
tal microphone interface, Digital Beep and analog PCBeep.
These features make the AD1984 the right choice for desktop
and notebook PCs where performance is key.
The AD1984 is available in a 48-lead, Pb-free frame chip scale
package in both reels and trays. See Ordering Guide on Page 20.
ADDITIONAL INFORMATION
This data sheet provides a general overview of the AD1984
SoundMAX codec’s architecture and functionality. Additional
information on the AD1984 is available in the AD1984 Pro-
grammers Reference Manual. Please contact your local ADI
sales representitive for more information. For information on
SoundMAX codecs and software see Analog Devices website at
