... VCC or VEE, therefore external resistor of 12pin is unnecessary. When to use BD3812F and BD3811K1 at the same time By using BD3812F and BD3811K1 at the same time, independent control of 8ch volume can be made. And control is available on a same bus line. In this case, be sure to set the SEL terminal setting to “setting 4”. ...

... BD3812F ●Notes for use (1) Numbers and data in entries are representative design values and are not guaranteed values of the items. (2) Although we are confident in recommending the sample application circuits, carefully check their characteristics further when using them. When modifying externally attached component constants before use, determine them so that they have sufficient margins by taking into account variations in externally attached components and the Rohm LSI, not only for static characteristics but also including transient characteristics ...
