2 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.

3 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).

4 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).
