Notes:
[1] Typical values @ TA = 25°C, VCC = 5.0V and timing measured at 50% levels.
[2] All Min/Max limits are guaranteed by Winbond via electrical testing or characterization. Not all specifications are 100 percent 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 K 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 percent over the commercial temperature 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. Therefore, from input to output, expect a 6 dB drop by nature of
passing through both filters.
