    I would like to assemble a similiar board replacing the trimmers with fixed resistors. Which is the range of the two trimmers R3 and R4?

    I still did not get how to tune this sensor.

    I’ve tried to set the vref in such a way to read 2.5V on vout when no current is flowing trough the sensor. The I apply a small current (e.g. 50 mA) and I set the gain in such a way to get a reading of about 4.5V.

    However I would like to have a vref very small and to use ideally the full range 0-5V to measure the current. I then tried to set the vref to 1V and the gain to the maximum, but all I can get is a reading of 1.37V in the vout when the same 50mA is flowing trough the sensor.

    Any idea?

No public wish lists :(
