Boards in 1 GitHub repository, designed in KiCad, that use the OPA2191ID by Texas Instruments (-18V~-2.25V、2.25V~18V -40℃~+125℃ 100nV/℃ 140dB 140uA 15nV/√Hz@1kHz 2 2.5MHz 2pA 4.5V~36V 5V/us 5pA 5uV 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 OPA2191ID’s symbol, footprint and pinout are on its own page.
