See filter curves in typical characteristics
The MIN, TYP, and MAX specifications are given for a 288-kHz SCF clock frequency. A slight error in the 288-kHz SCF may result from
inaccuracies in the MSTR CLK frequency, resulting from crystal frequency tolerances. If this frequency error is less than 0.25%, the
ADJUSTMENT ADDEND should be added to the MIN, TYP, and MAX specifications, where K1 = 100
[(SCF frequency – 288 kHz) / 288 kHz].
For errors greater than 0.25%, see Note 8.
§All typical values are at TA = 25
°
C.
NOTE 9: The filter gain outside of the passband is measured with respect to the gain at 1 kHz. The filter gain within the passband is measured
with respect to the average gain within the passband. The passbands are 150 to 3600 Hz and 0 to 3600 Hz for the bandpass and
low-pass filters respectively. For switched-capacitor filter clocks at frequencies other than 288 kHz, the filter response is shifted by the
ratio of switched-capacitor filter clock frequency to 288 kHz.
