NOTES:
1. Typical values @ TA = 25° C and 5.0 V.
2. All Min/Max limits are guaranteed by ISD via electrical testing or characterization.
Not all specifications are 100% tested.
3. Low-frequency cutoff depends upon the value of external capacitors (see Pin Descriptions).
4. From AUX IN; if ANA IN is driven at 50 mV p-p, the POUT=12.2 mW, typical.
5. With 5.1 KΩ series resistor at ANA IN.
6. TPDS is required during a static condition, typically overflow.
7. Sampling Frequency and Playback Duration can vary as much as ±2.25% over the commercial
temperature range and voltage range and ±5% over the industrial temperature and voltage range.
For greater stability, an external clock can be utilized (see Pin Descriptions).
8. Filter specification applies to the antialiasing filter and the smoothing filter.
