DAC Pair Powered Down Saves (Each)
ADC Pair Powered Down Saves (Each)
Mixer Power Control (and Associated Amps) Saves
MIC_BIAS Powered Down Saves
Powering down the MIC_BIAS powers down all port MIC_BIAS pins. This disables all microphone bias circuits, setting them to the high-Z
state.
Test conditions: 30 pF load, 2.0 MHz frequency, 3.3 V AV
