Component information
Component
Functional description
Cs
Bypass supply capacitor. Install as close as possible to the TS4962M 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 TS4962M differential gain (gain
= 300k
Ω/Rin
with Rin in kΩ).
Input
capacitor
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
-3dB cut-off frequency
= 1/(2*
π*Rin*Cin).
