AD4116 is the only is the only member of the family with a 10 MΩ input impedance and with additional low input voltage specifically design to have better performance at lower input ranges useful for current measurements which allowed extra rooms for any errors introduced by external sense resistor. Key differences are summarized in Table 1 below.
