Bypass supply capacitor. Install as close as possible to the TS4962M to
minimize high-frequency ripple. A 100nF ceramic capacitor should be
added to enhance the power supply filtering at high frequency.

Due to common mode feedback, these input capacitors are optional.
However, they can be added to form with R
