Application Circuit Example 1 (3-input type)
Usage Notes
1. The internal analog switch states are undefined when power is first applied. Signals should be muted externally until
the control data has been set up.
2. Cover the CL, DI, and CE pin signal lines with the ground pattern or use shielded cable for those lines to prevent the
high-frequency digital signals transmitted to the CL, DI, and CE pins from entering the analog system as noise.
3. Use bipolar capacitors if at all possible for capacitors for which no polarity is indicated.
4. We recommend making large changes in the electronic volume control setting, such as from 0 dB to –
∞ dB, by using
several intermediate steps as shown in the example below. This can reduce the switching noise associated with large
changes.
Example: 0 dB
→ –10 dB → –20 dB → –40 dB → –70 dB → –∞
