(ft) of the external filters is:

Taking in account that the internal filtering resistor (Rout) has a nominal value equal to 110k

Ω, the equation for

the external filter cut-off frequency may be simplified as follows:

The tolerance of the internal resistor can vary typically of ±20% within its nominal value of 110k

Ω; thus the cut-

off frequency will vary accordingly. A minimum capacitance of 320 pF for Cf(x,y,z) is required in any case.
