We in our lab use Scanning Tunneling Microscope (SPM 5500 Keysight Technologies) for measuring conductance of the organic molecule. For that we use log module amplifier which is shown in the attached file. However the module is not working anymore and we cannot order another piece because it is a discontinued product now. We do have a schematic of the circuit and want to get it design and made it in PCB. Edit: Please note that the opamp used in this schematic is discontinued. So the circuit design must include the equivalent replacement of OPA129U

Hi Sir, I am an Electronics Engineer currently working as an Integrated Circuit Layout designer. I have worked designing Digital and Analog circuits in the past, and have vast experience designing PCBs using a variety of software tools (as Altium Designer, Cadence Allegro and KiCAD). There exist plenty of substitutes for the discontinued Operational Amplifier, it is not a problem to design an equivalent circuit.   Please contact me so we can discuss the details. I can guarantee a first class work, offering unlimited reviews until you are completely satisfied with the final product. Regards,
