open-ephys/oe-acquisition-board-gen3
3rd Generation Open Ephys USB Acquisition Board
Boards in 6 GitHub repositories, designed in KiCad, that use the OPA365AID by Texas Instruments (-40℃~+125℃ 1 10pA 10pA 120dB 1uV/℃ 2.2V~5.5V 200uV 25V/us 4.6mA 4nV/√Hz@10kHz 50MHz 65mA ESD protection Rail-to-Rail Input, Rail-to-Rail Output SOIC-8 Operational Amplifier ROHS). See how each wires it, with its parts, size, README and files; the OPA365AID’s symbol, footprint and pinout are on its own page.
