(Note) Basically, mount ICs to the printed circuit board for use.
(If the ICs are not mounted to the printed circuit board, the characteristics of ICs may not be fully demonstrated.)
Mount 0.1µF capacitors in the vicinity of the IC PINs between PIN 1 (VDD2) and PIN 2 (VSS2), PIN 5 (AVDD) and PIN 6 (AVSS), PIN 11 (DVSS) and PIN
12 (DVDD), respectively.
Depending on the conditions of the printed circuit board, mount an additional electrolytic capacitor between the power supply and GND terminal.
For EMI protection, it is effective to put ferrite beads in the origin of power to be supplied to the BU2360FV from the board or to insert a capacitor (of not
more than 1), which bypasses high frequency desired, between the power supply and the GND.
