SELECTABLE HIGH PASS FILTER
Table 14 ADC Enable Control
Table 15 High Pass Filter Cut-off Frequencies (HPFAPP=1). Values in Hz.
A selectable high pass filter is provided. To disable this filter set HPFEN=0. The filter has two
modes controlled by HPFAPP. In Audio Mode (HPFAPP=0) the filter is first order, with a cut-off
frequency of 3.7Hz. In Application Mode (HPFAPP=1) the filter is second order, with a cut-off
frequency selectable via the HPFCUT register. The cut-off frequencies when HPFAPP=1 are shown
in Table 15.
Note that the High Pass filter values (when HPFAPP=1) are calculated with the assumption that the
SR register bits are set correctly for the actual sample rate as shown in Table 15.
