2 Application Component Information
Component
Functional Description
Cs
Bypass supply capacitor. To install as close as possible of the TS4962 to minimize high frequency rip-
ple. A 100nF ceramic capacitor should be add to enhance the power supply filtering in high frequency.
Rin
Input resistor to program the TS4962 differential gain (Gain = 300k
/Rin with Rin in k
)
Input
Capacitor
Thanks to common mode feedback, these input capacitors are optional. However, we can add then to
form with Rin a 1st order high pass filter with -3dB cut-off frequency = 1/(2*
π
