5-dB step attenuator inputs
These inputs must be driven by low-impedance circuits.

R5dBIN
Loudness circuit connections
Connect the high-band compensation capacitors between the CT1 and 5dBIN pins, and
connect the low band compensation capacitors between the CT2 and the V
M
pins.
5-dB step attenuator outputs
These outputs must be accepted by circuits with an impedance of between 47 k
and 1 M
.

R1dBOUT
Common connections for the volume control circuit. The impedance of the printed circuit board
pattern connected to these pins must be kept as low as possible. Since the LV
M
, RV
M
, and V
SS
pins are not connected internally, they must be connected externally as required by the various
specifications. When a single-sided power supply is used, the capacitors between V
M
and V
SS
become the residual resistance when the volume control is set at its maximum attenuation. This
means that care is required in selecting the values of these capacitors.
9
LV
M
Selection input for the address code in the data format. If this pin is connected to V
DD
, data will
be accepted when the address code is 9, and if connected to V
CC
, data will be accepted when
the address code is 8.
12
S
22
RV
M
Input pins for the serial data used to control the device.
These inputs must have an amplitude of 0 to 5 V. In applications in which any of microcontroller
CL, DI, or CE may go high in backup mode (when V
DD
= V
CC
= 0 V), the signal lines must have
series resistors of at least 2 k
inserted.
17
CL
Power supply connections. All these pins must be connected to the corresponding power
supply voltage. When power is first applied, the V
CC
voltage must not rise before V
DD
.
