Bypass supply capacitor. Install as close as possible to the TS4962 to
minimize high-frequency ripple. A 100nF ceramic capacitor should be added
to enhance the power supply filtering at high frequency.
Input resistor used to program the TS4962 differential gain (Gain = 300kΩ/R
with R
Because of common mode feedback these input capacitors are optional.
However, they can be added to form with R
