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