Tool/software:

Dear TI team,

I'm planning to use the INA180-Q1 for current monitoring.

Would it be possible to use the INA180-Q1 for photodiode current monitoring as well?

If so, I may consider switching to the INA2180-Q1.

Best Regards

Hi Jinho,

Our CSA devices are not recommended for a photodiode application due to the input bias currents that we have.

Look at these two short AppNotes about current measuring of photodiodes for the most common approaches:

You should also look at this design guide. I am looping in a different team who would be better suited for this if you need further assistance.

Best,

Holly
