Function

Input pin for channel 1 of the input selector switch block.

Input pin for channel 2 1 of the input selector switch block.

Adjusts input gains by using the resistance between this pin and the SELECT

OUT pin and by using resistance added to INA to IND.

Output pin of the input selector switch.

Input pin of the volume block.

Pin for setting the frequency characteristics of the loudness block.

Output pin of the volume block (1st stage). Connect this pin to VREF pin with C

connection to reduce switching noise.

Output pin of the volume block (2nd stage).

Input pin of the speaten filter block.

Pin for connecting filter of the speaten filter. (ch1)

Pin for connecting filter of the speaten filter. (ch2)

Reduce switching noise on speaten filter effect by using the capacitance

between pin9 and pin10.(ch1)

Reduce switching noise on speaten filter effect by using the capacitance

between pin39 and pin410.(ch2)

Output pin of the speaten filter block.

Input pin of the tone control block.

Pin for setting frequency characteristics of the tone control block for channel 1.

Pin for setting frequency characteristics of the tone control block for channel 2.

Output pin of the tone control block.

Resonant impedance (band-pass filter) connection pin for base section.

Output pin of bass boosting resonant buffer amp.

Input pin of bass boosting resonant buffer amp.

Final output pin of the ATT block.

Ground of the speaten filter speaten filter block. Apply 1/2Vcc.

Ground pin

Digital power supply pin.

Input pin of the control data. This pin inputs data in synchronization with CLOCK.

Clock input pin for serial data transfer.

Analog power supply pin.

IC signal ground. Apply 1/2Vcc.
