Boards in 1 GitHub repository, designed in KiCad, that use the TL081BCD by Texas Instruments (-20V~-2.25V、2.25V~20V 0℃~+70℃ 1 100dB 100pA 18nV/√Hz@1kHz 1mV 20V/us 26mA 2uV/℃ 300pA 4.5V~40V 5.25MHz 940uA Short-Circuit Protection、EMI filtering/RF suppression SOIC-8 FET Input Amplifiers ROHS). See how each wires it, with its parts, size, README and files; the TL081BCD’s symbol, footprint and pinout are on its own page.
