Sample Application Circuit (Three-input type)
Usage Notes
The states of the internal analog switches are undefined immediately after power is first applied. Applications should
apply muting to the outputs of this IC using external circuits until the control data has been set up.
The CL, DI, and CE pin lines should be shielded by the ground pattern or shielded lines should be used to prevent the
high-frequency digital signals that are transmitted over these lines from entering the analog system as noise.
We recommend that applications use a sequence of several smaller steps to approach the final setting when changing
the value of the volume control setting significantly. For example, the sequence shown below should be used when
changing from 0 dB to –
∞
. This can reduce switching noise.
Example: 0 dB
→
–10 dB
→
–20 dB
→
–40 dB
→
–70 dB
→
–
∞
No. 5681-10/12
