Boards using the CA3140
21 boardsBoards in 16 GitHub repositories, designed in KiCad, that use the CA3140 by Gcore (-15V~15V -40℃~+125℃ 1 10uV/℃ 30pA 3mV 4.5MHz 40nV/√Hz@1kHz 45mA 50pA 5mA 80dB 9V/us SOP-8 Operational Amplifier ROHS). See how each wires it, with its parts, size, README and files; the CA3140’s symbol, footprint and pinout are on its own page.
