We are looking at a signal that is typically 0 to 3V or -1.5 to 1.5V with the ability to measure the DC offset being important. We would like to have a higher fidelity of the signal as we are currently wasting most of the input range.
I have been considering changing the gain resistor dividers, however many of the components are missing silkscreen and I have not found an assembly drawing for the PCB.
