Usage Cautions

(1) Upon power application, the internal analog switch status is undefined. Use an external countermeasure such as

muting until data is set.

(2) When performing initial data setting after applying power, send the initial data once, and then send the initial setting

data.

(3) To ensure that the digital frequency signal sent to the CL, DI, and CE pins do not spill over to the analog signal

block, either guard these signal lines with a ground pattern, or perform transmission using shielded wires.
