We are using below circuit for current measurement, When DC1 voltage goes below 1.3v the voltage across R323 is going to ~1V(As like the wave form), even no current is flowing. Is this the behaviour of the INA138 or any issue with our circuit.
Please help us in resolving this...
For information VM_SW voltage is 18V, DC1 Voltage is 12V.
Thanks & Regards
