Other Parts Discussed in Thread: LMC6482
Hi
I'm using the INA196 to sense the current of my DC/DC stage. I have to change the output voltage from 0V up to 52V.
I have two issues:
1) Feedback voltage to the current sense resistor
When I set the output voltage to Vo = 0V, the INA196 drives a voltage to the current sense resister (around 0.6V). Is this an issue because this IC is not able to work with 0V at the output?
2) Output voltage can't drive the Opamp circuit
I use an Opamp circuit after the INA196. I don't know why, but the output of the INA196 will be pulled up (over 10k resistor) instead he stays at the current level. I could solve this issue by adding a buffer. But I think that shouldn't be.
Thanks for your help.
BR
