Hi Guys and Gals,
I am working with a sensor which outputs current in the range of +/- 72 mA.
I want to amplify (1.1976mA to 1.2024 mA) of the sensor output to (0 to 5V).
I am comfortable with current to voltage amplification but I am not sure how to do level shifting for the current i.e. 1.1976 mA corresponds to 0V and 1.2024 mA corresponds to 5V.
What I was thinking was, to connect the output from the sensor to a 1.1976 mA current sink (so that my 1.1976 mA to 1.2024 mA becomes 0 to 4.8 uA), and then apply 10^6 amplification using op-amp transimpedence amplifier. But I can not find any more information if this can be done.
Any seniors could shed some light if this can work? Or is there any other simpler way to achieve this?
Thank you in advance and please let me know if you need any more clarification from my side
Regards
Ajay
