Boards in 2 GitHub repositories, designed in KiCad, that use the OPA187ID by Texas Instruments (-18V~-2.25V、2.25V~18V -40℃~+125℃ 0.2V/us 1 100pA 100pA 100uA 140dB 1nV/℃ 1uV 20nV/√Hz@1kHz 30mA 36V 550kHz EMI filtering/RF suppression、Zero drift / auto-zero、Reverse-phase input protection Rail-to-rail output SOIC-8 Precision Op Amps ROHS). See how each wires it, with its parts, size, README and files; the OPA187ID’s symbol, footprint and pinout are on its own page.
