!APPLICATION NOTES
Note C1 can be adjusted rise and fall time of reference voltage at power on and off. Take care that the reduced C1makes sensitive to ripple of power supply. The Input impedance is designed about 48k ohms. The ground line should be inserted between each input lines to 3 - 6, 27 -30 Inputs avoid cross talk. Loudness frequency can be adjusted with external parts(See page 6) . Especialy, 8 and 25 pins should be kept from Loudness filter large signal lines such as digital signal lines or the other sound signal lines to avoid digitaly noise or cross talk in 7,8,25,26 Taps Loudness mode. Tone Bass and Treble cut off frequency can be adjusted with external parts(See page6). These pins should be kept 9,10,11,22,23, Tone filter from large signal lines such as digital signal lines or the other sound signal lines to avoid the digitaly noise or cross 24 terminals talk. 12,21 Tone outputs Output impedance is designed about 50 ohms. Balance Fedar Input impedance is designed about 24k ohms. 13,20 volume inputs Balance Fedar 14,15,18,19 volume Output impedance is designed about 50 ohms. outputs 2 VREF 16,17 I2C control signal ports These terminals should be inserted resistance about 100 ohms between terminal and signal source to reduce the digitaly noise. These lines should be kept from analog signal lines and or near by the chip to avoid digitaly noise. Inserted ground line between analog line and digital line should be recommended. Pin No. Function
