Hi,
I'm using INAEVM-MSOP8 to test INA333 with below configuration. V+=2.5V, V- = -2.5V. REF=0V, RG=1K, which sets GAIN=100.
Although IN- is not connected to GND, but I measured the common mode voltage is only 0.6mV.
IN+ -IN-, OUT=112mV
3mV 111.1mV
6mV 111.4mV
9mV 111.6mV
Then I tried from IN+ - IN- from 1mV to 10mV, OUT is always around 112mV.
What's wrong here?
