i looked at application of cn0217 in this application note there is example 1 :measuring low impedance paragraph that there is a set up configuration for measuring 1 uf capacitor :
Voltage Peak-to-Peak (V p-p): 1.98 V (Range 1)
Number of Settling Time Cycles: 15
MCLK: 16 MHz
RCAL: 20.1 Ω
RFB: 20.0 Ω
Excitation Frequency Range: 30 kHz to 30.2 kHz
Unknown Impedances: C3 = 1 μF(5.3 Ω at 30 kHz).
with this config i believe the ad5933 will saturate because the gain at the ti section is about 4=(RFB/unlnown impedance) and so the ad5933 adc will saturate.am i right about this?
