Boards using the OPA2277U

9 boards

Boards in 7 GitHub repositories, designed in KiCad, that use the OPA2277U by Texas Instruments (-18V~-2V、2V~18V -40℃~+85℃ 0.8V/us 10uV 140dB 1MHz 1nA 2 250nV/℃ 2nA 35mA 800uA 8nV/√Hz@1kHz Built-in compensation、Reverse-phase input protection SOIC-8 Precision Op Amps ROHS). See how each wires it, with its parts, size, README and files; the OPA2277U’s symbol, footprint and pinout are on its own page.
