Hello,
I created a current sensing circuit with INA240A1D recently. The electronic circuit is below.
I set the output to be midsupply voltage, but the wrong voltage is outputted.
Vcc = 5.0 [V]
(IN+) - (IN-) = 0.0[mV]
Out = 1.53 [V]
Before this phenomenon occurs, Out was the correct value, 2.5 [V] with 0.0 [mV] (IN+) - (IN-). Does this unbalanced midsupply voltage often occur as one of the failure modes? Do you come up with main causes?
