NOTE 1: Correct power supply bypassing is very important for optimizing SGM8951/2 performance. A 0.1µF and a 10µF capacitors
are always used to bypass VS pin of SGM8951/2. Please place these two capacitors as close to the SGM8951/2 VS pin as possible. A
large ground plane is also needed to ensure optimum performance.
