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). 26, 42 I Analog Supply Return (Ground).
