Boards in 1 GitHub repository, designed in KiCad, that use the MAX4656ESA+ by Maxim Integrated (Analog Devices) (-20V~-4.5V、4.5V~20V、9V~40V -40℃~+85℃ 1 10Ω 110ns 1:1 210MHz 67pF 75ns SOIC-8 Analog Switches, Multiplexers ROHS). See how each wires it, with its parts, size, README and files; the MAX4656ESA+’s symbol, footprint and pinout are on its own page.
