Function

VDD/2 voltage generation block. A capacitor must be

56

Vref

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

63

LVref

LVref (or RVref) and VSS become the residual resistance

50

RVref

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.

15

LINVIN1

Inverting inputs for the operational amplifiers that set the

34

RINVIN1

input gain.

Inverting inputs for the graphic equalizer operational

62

LINVIN2

amplifiers. Unnecessary frequency bands can be

51

RINVIN2

excluded and oscillation prevented by inserting arbitrary

capacitors between the INVIN2 and TOUT pins.

LTOUT

Tone control outputs

LVRIN

Volume control inputs

These must be driven by low-impedance circuits.

CE

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.
