In the datasheet of the AD9229 no value is given for the differential
resistance of the analog input. Can we assume a resistance of 1Mohm?


In Hold mode, the input resistance is > 1Mohm.
Track mode resistance is usually specified in the datasheet spec table. The DC
impedance is very high because of the capacitive load. However, the resistive
component of the DC impedance is around 10-15 ohm.
