Operating Conditions at Ta = 25°C
Note : Supply voltage V IO equal V DD , or V IO ≤ V DD & V IO ≥ 2.2 V
* Stabilize the service voltage so as not to cause the voltage change by the noise etc.
Operating Characteristics at Ta = 25°C, V CC = 3.0V, V DD = 3.0V, Volume =15/16, Soft Mute = 1/Soft Stereo = off
Output level set with Radio Control 1 of control register map (0Dh Bit0, Bit1,Bit5 set to ‘1’, ‘1’)
In addition, Set IF_OSC = 170kHz, IF_BW = 100% (Radio Control 1 : 0D Bit6, Bit7 set to ‘1’, ’1’)
Interface block allowable operation range at Ta = -20 to +70°C, V SS = 0V
Note : External clock input (pin 12) allows also input of the sine wave signal.
