16.1.7 Digital Filter
The LMP900xx has a fourth order rotated sinc filter that is used to configure various ODRs and to reject power supply frequencies
of 50Hz and 60Hz. The 50/60 Hz rejection is only effective when the device is operating at ODR
or the external CLK of 3.5717 MHz is used, then the LMP900xx will have the frequency response shown in
9.
