AD1989B
High Definition Audio SoundMAX Codec
The AD1989B audio codec and SoundMAX® software provide superior HD audio
quality that exceeds Vista Premium performance. The AD1989B has ten 101 dB
DACs and six 92 dB ADCs, three stereo headphone ports, C/LFE swapping, digital
and analog PCBeep, two independent S/PDIF outputs, and a S/PDIF input, making
the AD1989B the right choice for PCs where performance and a rich feature set are
primary considerations.
The jack retasking feature on this product supports various configurations including
7.1 on 5 jacks, 5.1 on 3 jacks, and front panel jack retasking.
The AD1989B is available in a 48-lead RoHS compliant lead frame chip scale
package in both reels and trays. See the Ordering Information table on the previous
page.
Special Software Features
The AD1989B audio codec also supports the following additional software features:
BlackHawk® and SoundMAX GUI contain all user audio controls
Voice input enhancement: Andrea Electronics best-in-class noise reduction,
beam forming, and echo cancellation
Output enhancement: Sensaura/Sonic Focus, spreading/downmixing, MP3
refinement, adaptive dynamics, compressor/limiter, speaker/graphic EQ,
Voice Clarity/X-MatrixTM, AGC, UI tuning tools
DTS®, SRS®, EAX® for gaming

these specifications at: http://www.intel.com/standards/hdaudio/
1.4 Absolute Maximum Ratings
Stresses greater than those listed below may cause permanent damage to the device.
This is a stress rating only; functional operation of the device at these or any other
conditions above those indicated in the operational section of this specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.

High-Z, 0 V, 1.65 V, 2.86 V, and 3.00 V (with 3.3 V on Pin 33).
Voltage Reference Filter.
CAUTION: DO NOT APPLY 3.3 V TO THIS PIN!
Filter connection for internal core voltage regulator.
This pin must be connected to filter caps: 10 μF, 1.0 μF, and 0.1 μF connected in
parallel between Pin 1 and DVSS (Pin 4).

Power and Ground
DVGPIO 3.3 V ± 10% 3 I GPIO and S/PDIF Out (1 and 2) Signal Level (independent of DVIO). Connect to
3.3 V ±10%.
DVIO 3.3 V ± 10%
or
DVIO 1.5 V ± 5.5%
4 I Connect to the I/O voltage used for the HD Audio controller signals.
DVSS 7 I Digital Supply Return (Ground).
DVDD 3.3 V ± 10% 9 I Digital Supply Voltage 3.3 V. This is regulated down to Pin 1 to supply the internal
digital core.
AVDD 3.3 V ± 5% 25, 38 I CAUTION: DO NOT APPLY 5.0 V TO THESE PINS!
Analog Supply Voltage 3.3 V ONLY.
Note: AVDD supplies should be well regulated and filtered as supply noise degrades
audio performance.
MIC_BIAS_IN 33 I Source for Microphone Bias Circuitry.
Connect this pin to 5.0 V via a low-pass filter. When connected this way the
AD1989B is capable of providing +3.95 V as a mic bias to all of the MIC_BIAS pins.
If 5 V is not available, connect this pin to +3.3 V (AVDD) via a low-pass filter. The
AD1989B produces a mic bias voltage relative to the AVDD supply
(typically 3.0 V @ AVDD = 3.3 V).
AVSS 26, 42 I Analog Supply Return (Ground). AVSS should be connected to DVSS using a
conductive trace under, or close to, the AD1989B.
GENERAL NOTES:
1. The symbols used in this table are defined as follows:
I = Input
O = Output
LI = Line level input
LO = Line level output
HP = Output capable of driving headphone load
MIC = Input supports microphones with MIC bias and boost amplifier
SWAP = Outputs can swap L/R channels (typically used to support C/LFE or shared C/LFE function).
