ISD1810 Product

5

ISD

2. Typical values @ T

A

= 25°C and 3.0 V.

3. All Min/Max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are

100 percent tested.

4. Oscillator stability may vary as much as ±5 percent over the operating temperature and voltage ranges.

5. Low-frequency cutoff depends upon value of external capacitors (see Pin Descriptions).

6. Filter specification applies to the antialiasing filter and to the smoothing filter.

7. Balanced input signal applied between MIC and MIC REF as shown in the application example. Single-ended MIC

or MIC REF recommended to be less than 100 mV peak to peak.
