●Notes for use (BU2362FV)
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 0.1
F capacitors in the vicinity of the IC PINs between 1PIN (VDD2) and 2PIN (VSS2), 5PIN (AVDD) and 6PIN
(AVSS), 11PIN (DVSS) and 12PIN (DVDD), respectively.
For the fine-tuning of frequencies, insert several numbers of pF in the 7PIN and 8PIN to GND.
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 supply to be fed to BU2362FV from the printed
circuit board or to insert a capacitor (of 1
or less), which bypasses high frequency desired, between the power supply and
the GND terminal.
*Even though we believe that the example of recommended circuit is worth of a recommendation, please be sure to thoroughly recheck the characteristics
before use.
