Notes:
[1]
Typical values @ TA = 25C and VCC = 5.0V.
[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.
