AKD4201-C Outline Chart Comment (1) J2 (LIN / RIN): Mimi-Jack It is a jack of analog input signals LIN / RIN. These signals are input to LIN pin / RIN pin. (2) J3 (LOUT / ROUT): Mimi-Jack It is a jack of analog output signals LOUT / ROUT. These signals are output from LOUT pin / ROUT pin. (3) TM1 (5V / 3.3V): Terminal It is a power supply terminal of 5V / 3.3V. It should be connected to power supply 5V/3.3V. For further details, refer to P3. “Set up the power supply lines”. (4) TM2 (GND): Terminal It is a ground terminal. It should be connected to GND. For further details, refer to P3. “Set up the power supply lines”. (5) SW1 (PDN): Toggle Switch It is a power down switch of AK4201. This should be set to H, after all power supply pins are supplied. <KM097400> 2008/11 -2- [AKD4201-C] Evaluation Board Manual Operation sequence 1) Set up the power supply lines. 1-1) The power of AVDD and PVDD is supplied from power supply jacks. <Default> Name Of jack 5V / 3.3V GND Color Of jack Red Typ.

Set up of power supply lines (The power of AVDD and PVDD is supplied from power supply jacks.) Note 1. Each supply line should be distributed from the power supply unit. AVDD and PVDD must be connected to the same power supply. Default Setting Connect to +5V / +3.3V 0V 3) The function of the toggle SW. (See the followings.) 4) Power on. SW1 (AK4201-PDN) should be kept “L”, until all power supply pins are supplied. SW1 (AK4201-PDN) should be set to “H”, after all power supply pins are supplied. The function of the toggle SW Upper is “H”, and lower is “L”. [SW1] (AK4201-PDN): Power down reset of AK4201. Keep “H” during normal operation. SW1 (AK4201-PDN) should be kept “L”, until all power supply pins are supplied. SW1 (AK4201-PDN) should be set to “H”, after all power supply pins are supplied. <KM097400> 2008/11 -3- [AKD4201-C] Revision History Date (yy/mm/dd) 08/11/12 Manual Revision KM097400 Board Revision 0 Reason Page Contents First Edition IMPORTANT NOTICE z These products and their specifications are subject to change without notice.
