Test conditions: 30 pF load, 2.0 MHz frequency, 3.3 V A
Powering down the MIC_BIAS powers down all port MIC_BIAS pins. This disables all microphone bias circuits set to 100% or 50%, setting them to the Hi-Z state. The
Function node D3 state powers down all nodes except for the V
background functions such as jack presence detection or analog pass-through are required. Mixer should be kept active when analog pass-through is required. MIC_BIAS
can be disabled if microphones are not in use in the power-down state.
