External Components
It is important to properly decouple the power supplies of
the chip with external capacitors that have good high
frequency properties.
The VS1, VS2, VS3, and VS4 pins are shorted on the PCB
level. Also GND1, GND2, GND3, GND4, GND5, GND6,
TEST, TEST1, and TEST2 are shorted on the PCB level.

1. The capacitor must be placed close to the AMIS−39101 pins on the PCB.
2. Both capacitors are optional and depend on the final application and board layout.
