It is possible to fine-control the current consumption by using the bias current control function (Bcont pin). When
Refer to the table below for the percentage of current regulation when using the bias current control function.

of the output amplifier will simultaneously change. Therefore, when using these functions, be sure
to sufficiently evaluate the picture quality.
