NOTES:
9. The above filter specifications are for a switched-capacitor filter clock range of 288 kHz
±
2%. For switched-capacitor filter clocks
at frequencies other than 288 kHz
±
2%, the filter response is shifted by the ratio of switched-capacitor filter clock frequency to
288 kHz.
10. 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 300 to 3400 Hz and 0 to 3400 Hz for the bandpass and
low-pass filters respectively.
11. The noise is reffered to the input with a buffer gain of one. If the buffer gain is two or four, the noise figure is correspondingly reduced.
The noise is computed by statistically evaluating the digital output of the A/D converter.
