Boards in 2 GitHub repositories, designed in KiCad, that use the OPA197ID by Texas Instruments (-18V~-2.25V、2.25V~18V -40℃~+125℃ 1 10MHz 120dB 1mA 20V/us 25uV 2pA 4.5V~36V 5.5nV/√Hz@1kHz 500nV/℃ 5pA 65mA EMI filtering/RF suppression、Reverse-phase input protection Rail-to-Rail Input, Rail-to-Rail Output SOIC-8 Precision Op Amps ROHS). See how each wires it, with its parts, size, README and files; the OPA197ID’s symbol, footprint and pinout are on its own page.
