I need to create a negative high voltage reference voltage (-80V), I think the attached circuit will do the job.
It uses a precision +5V reference, and a high voltage op-amp in the inverting configuration to produce -80V output. The op-amp can handle +/-50V or 100V rail supply voltages. Im thinking of using unbalanced supply voltages of +10/-90V so the the output can reach -80V.
Does anyone have a reason that this might not work ? or have any better ideas ? I hope that the circuit will have very little voltage drift, it doent need to sink/source much current.
Thanks for your help.
