Boards in 1 GitHub repository, designed in KiCad, that use the AD624ADZ by Analog Devices (-18V~-6V、6V~18V -25℃~+85℃ 1 15us 200uV 20pA/℃ 25MHz 2uV/℃ 35nA 4nV/√Hz@1kHz 50nA 5V/us 5mA 70dB External resistor gain、Digitally programmable gain、Built-in compensation CDIP-16-SB Instrumentation Amplifiers ROHS). See how each wires it, with its parts, size, README and files; the AD624ADZ’s symbol, footprint and pinout are on its own page.
