Common pins for the main volume block, fader volume block, tone block, gain
control block, and input switching block.
Since the capacitors connected between LVref/RVref and VSS become the
residual resistance when the volume control is at maximum attenuation, the
values of these capacitors must be chosen carefully.
The applied voltage must never exceed VDD.
0.488 VDD voltage generation block. A capacitor must be connected between
Vref and VSS to suppress power supply ripple.
Fader outputs. The front and rear systems can be attenuated independently.
The amount of attenuation is the same in the left and right channels.
Low impedance operational amplifier outputs
Fader inputs
Must be driven from low-impedance circuits.
Tone control outputs
Connections for the bass and treble compensation capacitors for the tone
control circuit
Connect high-band compensation capacitors between T1 and T2.
Connect low-band compensation capacitors between T2 and T3.
Loudness pins. Connect high-band compensation capacitors between
LCT1/RCT1 and L10dBIN/R10dBIN, and connect low-band compensation
capacitors between LCT2/RCT2 and LVref/RVref.
