*最適な動作条件とするためにはGND ラインは 4 番端子を中心にした 1 GND
配線とし、部品を最短で配置することが必要です。パッケージの裏面ヒートシ
ンクにつながる GND の銅箔面積を大きくすることで、放熱効果が上がります。
*The circuit board layout is recommended as follows:
Other components are connected as close as possible to the SI-8005Q.
Each ground of all components is connected at one point area.
The heat radiation characteristics will be better when copper foil area connected to
heat sink on the reverse side of package is enlarged. The copper foil area is GND.
