Function

Input pins for the 10 dB step attenuator. Must be driven from a low impedance.

Loudness connections. Connect a high band compensation capacitor between

CT1 and 10dBIN and connect a low band compensation capacitor between CT2

and Vref.

Output pins for the 10 dB step attenuator. These outputs must be received by a

load of about 1 MΩ.

Input pins for the 2 dB step attenuator. Must be driven from a low impedance.

Output pins for the 2 dB step attenuator. These outputs must be received by a

load of about 1 MΩ.

7

LVref

Volume circuit common pins. The impedance of the pattern connected to these

pins should be kept as low as possible.

Since the capacitors between Vref and VSS form the residual resistance

components when the volume is cut, adequate care must be taken in

RVref

determining the value of these capacitors.

Pin that selects the address code in the data format. Data will be accepted for

12

S

an address code of 88 when this pin is tied to VDD, and for an address code of

89 when tied to VSS.

CL

Serial data and clock inputs for control

10

DI

Chip enable. The internally latched data is written and the analog switches

operate when this pin goes from high to low. Data transfer is enabled when this

pin is at the high level.

8

VDD

These pins must be connected to the power supply.
