3.1.1.2 Input Frequency Response
The following table shows the association between component values and maximum input frequency response.
Input Component
A0 C1
B0 C2
C0 C3
A1 C4 30 kHz 300 kHz * 1 MHz
B1 C5 10nF Capacitor 1nF Capacitor 330pF Capacitor
C1 C6
A2 C7 * Default
B2 C8
C2 C9
To reduce the cut-off frequency, larger capacitor values should be used. The values provided in the table are provided as an
example and have been simulated over the full operating temperature range.
3.1.1.3 Input EMI Protection
The design allows for additional enhanced EMI protection by replacing the following components with a suitable SMD
coil.
