3 / 32 page  TS4962M Application Component Information 3/32 2 Application Component Information Table 3. Component information Component Functional Description Cs Bypass supply capacitor. To 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 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 -3dB cut-off frequency = 1/(2* π*Rin*Cin). Figure 1.
