Individual block power savings
Guaranteed but not tested.
Measurements reflect main ADC.
RMS values assume sine wave input.
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 high-Z state. The
0 Ω and high-Z states remain unaffected by the MIC_BIAS power state.
