Because we need a 80mA current source, so place a 12.5ohm on Rsense.
And try to set a test environment as below.
(1)Force 0.1V , measure I (Selected Current Range:±external current range.)
I try to short test point with ground point and then expected value is 80mA.
Unfortunately, value is around 2.5mA.
(2)Force 5V and connect 500ohm, current is 9.6mA.
Do you have any advise to me?
