Notes:
[1] _{These specifications apply with ROSC = 100KΩ, unless stated.}
[2] _{Typical values @ TA = 25° and VCC = 3.0V.}
[3] _{All Min/Max limits are guaranteed by Winbond via electrical testing or characterization. Not all}
specifications are 100 percent tested.
[4] _{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)
[5] _{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.
