Kavindu,I am not clear what the CVin vertical axis on your graph show - there is no such label on your schematic (see below) and with the componets values you use there is no node with potential around...
View ArticleForum Post: RE: INA2332: huge gain difference
Hello Tobias,Here are a couple suggestions:1) Try replacing the load cell with a known differential voltage. Given that your gain is 1000V/V and 550mV<Vcm<3.8V when Vs=5V, a 2mV differential...
