Component information
Bypass supply capacitor. Install as close as possible to the VCCA pin of the
TS4961T to minimize high-frequency ripple. A 1 uF ceramic capacitor should be
added to enhance power supply filtering at high frequencies (see below).
Bypass supply capacitor. Install as close as possible to the VCCS pin of the
TS4961T to minimize high-frequency ripple. A 100 nF ceramic capacitor should
be added to enhance power supply filtering at high frequencies.

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