Component
Functional Description
Cs
Bypass supply capacitor. To 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.
Rin
Input resistor to program the TS4962 differential gain (Gain = 300k
/R
in with Rin
in k
).
Input Capacitors
Cin
Thanks 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 a
-3dB cut-off frequency = 1/(2*
π*R
in*C
in).
