AD1882A

Table 6. AD1882A Pin Descriptions (Continued)

Mnemonic

Pin No. Function

Description

POWER AND GROUND

DV_IO3.3 V 10%

Connect to the I/O Voltage Used for the HD Audio Controller Signals.

DV_IO1.5 V 5.5%

DV_GPIO

DV_SS

DV_DD(3.3 V)

Connect to 3.3 V digital supply to power the GPIO and S/PDIF pins.

Digital Supply Return (Ground).

Digital Supply Voltage 3.3 V. This is regulated down to DV_COREon Pin 1 to supply the

internal digital core internal to the AD1882A.

AV_DD(3.3 V)

MIC_BIAS_IN

AV_SS

25, 38

CAUTION: DO NOT APPLY 5.0 V TO THESE PINS!

Analog Supply Voltage 3.3 V ONLY.

Note: AV_DDsupplies should be well regulated and filtered as supply noise degrades

audio performance.

Source Power for Microphone Bias Circuitry. Connect this pin to 5.0 V via a low-pass

filter. When connected this way, the AD1882A is capable of providing 3.9 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 (AV_DD)

via a low-pass filter.

26, 42

Analog Supply Return (Ground). AV_SSshould be connected to DV_SSusing a

conductive trace under, or close to, the AD1882A.

The symbols used in this table are defined as: 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).
