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 VM 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 LVM, RVM, and VSS
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 VM and VSS
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
LVM
Selection input for the address code in the data format. If this pin is connected to VDD, data will
be accepted when the address code is 9, and if connected to VCC, data will be accepted when
the address code is 8.
12
S
22
RVM
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 VDD = VCC = 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 VCC voltage must not rise before VDD.

Unconnected (NC) pins
Do not connect any signals or devices to these pins.
