NOTE 1: Correct power supply bypassing is very important for optimizing SGM8941/2 performance. A 0.1µF and a 10µF capacitors
are always used to bypass V_S pin of SGM8941/2. Please place these two capacitors as close to the SGM8941/2 V_S pin as possible. A
large ground plane is also needed to ensure optimum performance.
