Boards in 3 GitHub repositories, designed in KiCad, that use the OPA4170AID by Texas Instruments (-1.35V~18V -40℃~+125℃ 1.2MHz 1.8mV 120dB 145uA 15pA 15pA 17mA 19nV/√Hz@1kHz 2.7V~36V 20V/us 2uV/℃ 4 ESD protection、EMI filtering/RF suppression Rail-to-rail output SOIC-14 Operational Amplifier ROHS). See how each wires it, with its parts, size, README and files; the OPA4170AID’s symbol, footprint and pinout are on its own page.
