Hi all,
I'm trying to get a reading from a Digi-Star load cell.
I'm using the INA122 instrumentation amplifier, the schematic is attached.
Nothing complicated, I connect the cell output directly to the ina122 inputs, and I use a low gain (10K Rg).
Single power supply, 5V, to power the amplifier.
The problem is that at the output I have about the supply voltage.. about 4,8 V.
I used the same schematic as the one in the datasheet..
I don't understand why this behavior.. Any idea?
Thanks
