REXT = 16 Ω 
REXT = 600 Ω, Aux In=1.25Vp-p
Peak-to-Peak; REXT = 16 Ω
 Typical values @ TA = 25ºC, VCC = 5.0V and timing measured at 50% levels.
 All Min/Max limits are guaranteed by Winbond via electrical testing or characterization. Not all specifications are 100 percent tested.
 Low-frequency cutoff depends upon the value of external capacitors (see Pin Descriptions)
 From AUX IN; if ANA IN is driven at 50 mV p-p, the POUT = 12.2 mW, typical.
 With 5.1 K Ω series resistor at ANA IN.
 TPDS is required during a static condition, typically overflow.
 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)
 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.
