When the INAS pin = “L”, this pin should be connected to VSS2-5.
When the INAS pin = “L”, this pin should be connected to VSS2-5.
When the INAS pin = “L”, this pin should be connected to VSS2-5.
When the PDN pin= “L”, this pin outputs “H”.
“L”(connected to the ground): Synchronous mode.
“H”(connected to DVDD1-4) : Asynchronous mode.
“H”: Power up, “L”: Power down reset and initializes the control register.
The AK4129 should be reset once by bringing PDN pin = “L” upon power-up.
“L”(connected to the ground): Stereo mode.
“H”(connected to DVDD1-4) : TDM mode.
This pin should be connected to VSS2-5.
This pin should be connected to VSS2-5.
