Notes:
[1] _{Typical values @ TA = 25ºC, 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 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.
