Re: Impedance Measurement by Frequency Sweep

Hi Shehzad,

The ADuCM350 needs a minimum series resistance of 100 ohm to maintain IN-AMP stability.Hence,you can not measure 30 Ohms with ADuCM350. Please refer to the AFE Measurement range FAQ for more details:ADuCM350 FAQ AFE Measurement Circuit Impedance Range

With this configuration ,you can select RTIA accordingly and use as RTIA will be more than 100 ohms.

Thanks
