Functional description
Bypass supply capacitor. Install as close as possible to the TS4962M to
minimize high-frequency ripple. A 100 nF ceramic capacitor should be
added to enhance the power supply filtering at high frequency.
Input resistor to program the TS4962M differential gain (gain = 300 kΩ/Rin
with Rin in kΩ).
Due to common-mode feedback, these input capacitors are optional.
However, they can be added to form with Rin a 1st order high-pass filter with
-3 dB cut-off frequency = 1/(2*π*Rin*Cin).
