* Stabilize the service voltage so as not to cause the voltage change by the noise etc.

Operating Characteristics

at Ta = 25°C, VCC = 3.0V, VDD = 3.0V, Volume =15/16, Soft Mute = 1/Soft Stereo = off

with the designated test circuit

Output level set with Radio Control 1 of control register map (0Dh Bit0, Bit1,Bit5 set to ‘1’, ‘1’)

Control 2 of control register map (0Dh Bit1 set to ‘1’)

In addition, Set IF_OSC = 170kHz, IF_BW = 100% (Radio Control 1 : 0D Bit6, Bit7 set to ‘1’, ’1’)
