Boards in 1 GitHub repository, designed in KiCad, that use the TSV521ICT by STMicroelectronics (-40℃~+125℃ 1 1.15MHz 1.5mV 1pA 1pA 2.7V~5.5V 30uA 3uV/℃ 55mA 72dB 740V/ms Rail-to-Rail Input, Rail-to-Rail Output SC-70-5 Operational Amplifier ROHS). See how each wires it, with its parts, size, README and files; the TSV521ICT’s symbol, footprint and pinout are on its own page.
