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.
