Component

Functional description

CSA

Bypass supply capacitor. Install as close as possible to the VCCA pin of the

TS4961T to minimize high-frequency ripple. A 1 uF ceramic capacitor should be

added to enhance power supply filtering at high frequencies (see below).

CSS

Bypass supply capacitor. Install as close as possible to the VCCS pin of the

TS4961T to minimize high-frequency ripple. A 100 nF ceramic capacitor should

be added to enhance power supply filtering at high frequencies.

RIN

Input resistor to program the TS4961T differential gain (gain = 300 k

Ω/RIN with

RIN in kΩ).

CIN

Because common mode feedback is implemented, these input capacitors are

optional. However, they can be added to form with RIN a 1st order high pass filter

with a -3 dB cut-off frequency = 1/(2*

π*RIN*CIN).
