Refer to
for further information on the input bias current. This current varies based on the input common-mode voltage. Additionally, the input bias current
flowing to the +IN pin is also the supply current to the internal LDO.

The differential input voltage is specified as 250 mV typical because the output is internally clamped to 5 V. This ensures the output voltage does not exceed 5 V and
can interface and not cause damage to any typical converter, regardless of the high voltage present at the inputs of the AD8217 (up to 80 V).

See
and
for further information on the output range of the AD8217 with various loads. The AD8217 output clamps to a maximum voltage of 5.6 V
when the voltage at pin +IN is greater than 5.6 V. When the voltage at +IN is less than 5.6 V, the output reaches a maximum value of (V+IN 100 mV).
