Other Parts Discussed in Thread: OPA134
Hello
We are new to this board and are not sure of having read the manual properly. The issue is we get 4 mV or 40 mV when we use the OPS amplification even if the differential signal we want to amplify is not connected. In our application sending 0V when the system is in an idle state is very important.
Our setup is
- Both switches are at GND (we switch PD_SW for non-amplification)
- V+ is at 6V, V- is at -6V and the GND is connected
- Use J7 as output (J5 for non-amplification)
- We have not removed or added any resistance to the board
So, how can we get 0V at the output?
Thank you
Javi
