Input impedance AFE MKM34Z256

diego_asanza — Wed, 19 Feb 2020 15:19:27 GMT

Dear all,

Where can I find more information on the input impedance of the integrated sigma-delta adc in MKM34Z256VLx7? The datasheet has some information about the sar converter, but I cannot find any reference to the input impedance of the sigma-delta converter.

Thanks,

Diego
