It is an useful PCB to test SOIC8 instrumentation amplifiers which are pin compatible with INA826 by Texas Instruments, allowing to use them in breadboards. A charge pump is provided to generate the negative power rail from the positive one provided. Filtering and decoupling capacitors are also provided, as well as an output load resistor. The board as a whole is a painless way to test these amplifiers.
