Usage Cautions
(1) Data transmission at power ON
(2) Description of zero-cross switching circuit operation
The LC75411ES and 75411WS have a function to switch zero-cross comparator signal detection locations, enabling
the selection of the optimum detection location for blocks whose data is to be updated. Basically, the switching noise
can be minimized by inputting the signal immediately following the block whose data is to be updated to the zero-
cross comparator, so it is necessary to switch the detection location every time.
• The status of internal analog switches is unstable at power ON. Therefore, perform muting or some other
• At power ON, initial setting data must be sent once in order to stabilize the bias of each block in a short time.
