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). 18 Conexant DSH-202015A 3/2/09 AD1989B Data Sheet 1.7 Table 10.
