VREF should be kept active when 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. 2 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 0 Ω and Hi-Z states remain unaffected by the MIC_BIAS power state.
