Boards using the OPA189ID
9 boardsBoards in 9 GitHub repositories, designed in KiCad, that use the OPA189ID by Texas Instruments (-18V~-2.25V、2.25V~18V -40℃~+125℃ 1 1.7mA 140pA 14MHz 168dB 20V/us 3uV 4.5V~36V 5.2nV/√Hz@1kHz 5nV/℃ 65mA 70pA EMI filtering/RF suppression、Zero drift / auto-zero、ESD protection、Reverse-phase input protection Rail-to-rail output SOP-8 Precision Op Amps ROHS). See how each wires it, with its parts, size, README and files; the OPA189ID’s symbol, footprint and pinout are on its own page.
