VDD/2 voltage generator block. Connect capacitors between
Vref and VSS to minimize the effects of power supply ripple.
Pins common to volume control, tone control, and input
selection blocks. Select the capacitors between these pins
and VSS carefully as they contribute residual resistance
when the volume is turned down. The voltage must never
exceed VDD.
Operational amplifier inverted input for specifying input gain.
Operational amplifier inverted input for specifying graphic
equalization. Connecting a capacitor across INVIN2 and
TOUT permits the removal of unwanted bands and reduces
the risk of oscillation.
Tone control output
Volume control input. Must be driven with low-impedance
circuits.
Volume control output
Chip enable pin. The chip uses falling edge timing to write
data to the internal latch and shift analog switches. The high
level enables data transfer.
Serial data and clock input used for control
Leave unconnected
