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.

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%

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).
