I'm evaluating the supply current for AD8602: Precision CMOSSingle-Supply, Rail-to-Rail Amplifier.
But I wonder whether I can evaluate it correctly and my circuit is suitable.
It would be very appriciated giving me some advice.
Please refer to the figure.
(Voltage follower, Vin+=GND, Vin- is tied to Vout, No Road)
And I have one more thing to make sure.
The datasheet says the condition of supply current is mesured with Vout=0V.
But Vout of my circuit is not 0V. There is 0.8mV.
I think It is due to saturated Vout range and Voffset.
Is it possible to set 0V?
