Boards in 1 GitHub repository, designed in KiCad, that use the OPA2317ID by Texas Instruments (-2.75V~-900mV、900mV~2.75V -40℃~+125℃ 0.15V/us 1.8V~5.5V 108dB 2 20uV 275pA 300kHz 35uA 400pA 50nV/℃ 55nV/√Hz@1kHz 5mA EMI filtering/RF suppression、Zero drift / auto-zero 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 OPA2317ID’s symbol, footprint and pinout are on its own page.
