Description

A1

VCC

Power Supply Input. The voltage on the VCC pin is monitored on the ADM8641. It is recommended to

place a 0.1 μF decoupling capacitor between the VCC pin and the GND pin.

A2

GND

Ground. Both GND pins on the ADM8641 must be grounded.

DNC

Do Not Connect. Do not connect to this pin.

B2

GND

Ground. Both GND pins on the ADM8641 must be grounded.
