Functional description

CS

Rin

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/Rin with Rin in kΩ).

Because of common-mode feedback, these input capacitors are optional.

However, they can be added to form with Rin a 1st order high-pass filter with

-3 dB cut-off frequency = 1/(2*π*Rin*Cin).
