Other Parts Discussed in Thread: OPA693, OPA858, OPA855
Tool/software:
I am designing an amplifier to amplify the signal from a photomultiplier tube (PMT) and digitize the output using a standard digitizer.
I used a circuit incorporating the OPA857 and OPA693, but I am not getting any output signal. While adjusting the offset with the potentiometer, I can observe changes in the DC voltage level, but no signal is present.
I would greatly appreciate any assistance in identifying potential issues with the circuit or improving its design.
