Pins common to volume control, tone control, and input

selection blocks. Select the capacitors between these pins

when the volume is turned down. The voltage must never

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
