Please refer to these specifications at: http://www.intel.com/standards/hdaudio/ Rev. 0 | Page 6 of 16 | January 2007 AD1884 POWER DOWN STATES Parameter Function Node in D0, All Nodes Active Function Node in D31 Codec in RESET Individual Block Power Savings DAC Pair Powered Down Saves (Each) ADC Pair Powered Down Saves (Each) Mixer Power Control (And Associated Amps) Saves MIC_BIAS Powered Down Saves2 1 IDVDD Typ 58 21 3 6 5 0 0 IAVDD Typ 31 2 3 5 3 2 0.5 Unit mA mA mA mA mA mA mA Function node D3 state powers down all nodes except for the VREF, Mixer and MIC_BIAS nodes which have independent power controls. 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.
