I am using AD7746 for voltage measurement (along with a capacitance measurement
using the other channel.). What is the input impedence of the voltage channel
ADC?

 

The voltage inputs use switched capacitance technology (Σ-Δ ADC).
The Average VIN Input Current is 300 nA/V The Average REFIN Input Current is
400 nA/V
