efit of InGenius, while providing a discharge path for
charge in the input coupling capacitor. Choose capac-
itors large enough to present minimal impedance to
the lowest signals of interest, compared to the differ-
ential input impedance of the InGenius IC (48 kΩ). If
desired, this may be combined with the RF protec-
tion of Figures 10 or 11, and ESD protection of fig-
ures 13 or 14.
