Functional description
CS
Rin
Input capacitor
Bypass supply capacitor. Install as close as possible to the TS4962 to
minimize high-frequency ripple. A 100nF ceramic capacitor should be added
to enhance the power supply filtering at high frequency.
Input resistor used to program the TS4962 differential gain (Gain = 300kΩ/Rin
with Rin in kΩ).
Because of common mode feedback these input capacitors are optional.
However, they can be added to form with Rin a 1st order high pass filter with
-3dB cut-off frequency = 1/(2*π*Rin*Cin).
