VDD/2 voltage generation block. A capacitor must be
inserted between Vref and VSS to suppress power supply
ripple.
Common pins for the volume control, tone control and
input switching blocks. Since capacitors inserted between
LVref (or RVref) and VSS become the residual resistance
when the volume control is set at maximum attenuation,
the values of these capacitors must be chosen carefully.
A voltage higher than VDD must never be applied.
Inverting inputs for the operational amplifiers that set the
input gain.
Inverting inputs for the graphic equalizer operational
amplifiers. Unnecessary frequency bands can be
excluded and oscillation prevented by inserting arbitrary
capacitors between the INVIN2 and TOUT pins.
Tone control outputs
Volume control inputs
These must be driven by low-impedance circuits.
Volume control outputs
Chip enable
Data is read into the internal latches and the analog
switches operate when this pin goes from high to low.
Data transfer is enabled when this pin is high.
Serial data and clock connections for chip control
