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 Ω 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.
