DATA SHEET

Filter Settings: FS and resolution of HVAL

The FS register defines the sampling frequency of the

built in digital low-pass filter (see Table 3–2 on

page 11).

Fig. 3–3 shows the magnitude of the transfer function

for all recommended settings of FS at the pass band

and stop band. Fig. 3–4 is a zoom-in of the magnitude

at the pass band.
