Boards using the OPA2134PA

9 boards

Boards in 7 GitHub repositories, designed in KiCad, that use the OPA2134PA by Texas Instruments (-18V~-2.5V、2.5V~18V -40℃~+85℃ 0.00008% 106dB 2-Channel 5mA PDIP-8 Audio Amplifiers ROHS). See how each wires it, with its parts, size, README and files; the OPA2134PA’s symbol, footprint and pinout are on its own page.
