Oscillator stability may vary as much as +5% over the operating temperature and voltage ranges. (Only
the 7.5 sec duration of I1806 and 10 sec duration of I1810 are tested/guaranteed)

Low-frequency cutoff depends upon value of external capacitors (see Pin Descriptions)
[6]
Filter specification applies to the anti-aliasing filter and to the smoothing filter.
[7]
Balanced input signal applied between MIC and MIC REF as shown in the applications example. Single-
ended MIC or MIC REF recommended to be less than 100 mV peak to peak.
